Well, if you are a gamer, you will surely know a thing or two about graphics quality. The best graphics cards produce best quality of image. Similarly, GPUs of not so good quality can distort the images to an unimaginable level. So, it is worthwhile comparing different products when it comes to graphics cards. nVidia and ATi Radeon are two such GPUs that have been in the market for quite sometime now. So, how do they compare against each other? Let’s see the view point…

From a bird’s eye point of view, there hardly exists much difference between nVidia and ATi Radeon graphics cards. The technical competence of both these products can meet the requirements of even a hardcore techie. All said and done, there are few minor differences that exist between these two iconic products. For instance, the latest version of graphics cards, i.e. dual 3D-card was introduced by nVidia and is yet to be associated with ATi. ATi Radeon GPUs are not sophisticated enough to match the brilliance of 3D effects that one can associate with nVidia graphics cards. So, if you are a hardcore gamer and like 3D effects coming out of it, nVidia GPUs offer you with a choice. However if you are an average user ATi Radeon GPUs should suffice.

If you have invested a lot in the recently launched Windows 7 package that come with DirectX 11 then you will be glad to know that both nVidia and ATi Radeon will complement your existing infrastructure. Both these GPUs will provide users with quick frame speeds, multi-screen gaming qualities and high quality graphics to go along with all other features. Interestingly, both these types of graphics cards are reasonably priced and will offer you a good value for your money. So, even if you are limited on your budget these are the GPUs for you.

nVidia graphics cards are a wonderful addition to your computer as it is known to increase the flexibility of the machine considerably. The advance version of these cards features television software, TV cable input and a Dual monitor. On the other hand, ATi Radeon GPUs come with a one slot cooler to provide their own cooling solutions. Most of these cards are manufactured with 40nm technology. This is mainly responsible for decreasing the heat generated while in operation and increase in energy efficiency.

The most recent versions of nVidia graphics cards allows you to connect a computer video card with to a cable television feed and can then transfer the output signal to a monitor. This is really beneficial if your TV needs an AV cable signal or a VGA. These are some of the features that are not visible in ATi Radeon GPUs. As such, ATi GPUs are not suitable for high-end gaming solutions. But if you are content in playing lower-end or mid level games and are also limited in your budget, ATi GPUs will perform in a much similar way to nVidia graphics cards.

Dedicated graphics cards, which we will be discussing in this guide, are needed if you want to do 3D gaming or watch high definition movies (even though it may sometimes suffice with a powerful CPU and lot’s of internal RAM)

Important Specifications to Consider When Choosing a Graphics Card

GPU
GPU stands for “Graphic Processing Unit” and is the main controlling circuit on every graphics card. The GPU is the most determinant feature of every graphics card when it comes to the overall performance and speed. The two biggest manufacturers of GPUs are NVIDIA and ATI (which is owned by CPU manufacturer AMD). They do the reference designs for each new generation of graphics card. But most graphics cards are sold by other manufacturers who produce their own flavour of the reference cards from NVIDIA and ATI. Examples of those manufacturers are MSI, Asus, ECS Elitegroup, XFX and more.

Examples of recent generations of graphic GPUs from NVIDIA are; GeForce 8500/8600/8800/9800 GT/GTX/GX2 and GTX 260/280. ATIs latest generations of graphics cards are: RADEON HD 3850/4850/4870 in different versions.

RAM
It is also important to consider the amount and type of the onboard RAM of the graphics card, which is a different thing than the RAM of your computer. The RAM is important for a number of technical reasons we will not go into further here. But in short you should go for a graphics card with at least 256MB of RAM. The type of RAM is less important, but we recommend that you buy a graphics card with the second or later generation of GDDR (GDDR2 or later).

Different Slot Types
There are three different slots available on the PC market. The “slot” is where you connect the graphics card on the mainboard of your computer. You must verify which type of slot your mainboard has before purchasing a graphic card, or you may waste money on something you cannot use. The available slots are PCI (very old), AGP (old) or PCI express (today’s standard). All fairly recent bought computers are outfitted with a PCI Express slot, but be sure to check it. PCI express is the newest technology and allows the largest bandwidth which means better performance for you.

External Connectors
The connecters on the graphics cards are also important. Standard analog VGA connectors have been replaced by DVI (digital) connectors. The DVI connector is a must, some cards even come with two DVI connectors which will allow you to connect an extra display. Additional external connectors to look for are:
oHDMI, which will enable you to connect your computer to a plasma or LCD-TV. (This can also be done through a DVI connector with a DVI/HDMI converter)
oS-Video outputs are used to connect the PC to an older style VCR or TV and allow outputting the same display as present on your screen.
oDB-15/VGS/SVGA connectors are basically utilized for a standard output to an analog monitor. Good if you have an old monitor.

Considering your budget
Of course, you financial possibilities will limit your purchase options too. Let’s take a look of what you can expect depending on how much you want or can afford. Remember that graphics cards are products with short cycles so suggestions below are only guide lines.

Low budget graphic cards
We are talking about spending $50 to $80, what can you expect?

In this lower budget level the most popular and valuable GPUs from ATI and NVIDIA are the ATI Radeon HD 3650 and the NVIDIA GeForce GTX 260 and 8600GT/GTS. These cards typically carry a RAM of 256MB-512MB depending on model and manufacturer. There are no problems to find cards with multiple DVI connectors and some even carry a HDMI connector.

These types of cards are suitable for silent HTPCs and media centres since you can get them with silent passive coolers. We cannot recommend the entry level graphics cards for hardcore gaming rigs, even though they will play some older games with no sweat.

Medium priced graphic cards
In this segment, with prices from $80 to $250, you will find graphics cards with good performance even for gaming. You should be aware, because as we said, this is a fast moving market and you can sometimes find real bargains on the current generation of graphics cards when the next generation cards are introduced to the market. Prices drops fast when retailers and e-tailers have to make place in their stock for the new generation of cards.

As always we recommend you to read expert reviews of graphics cards to find which the leading expert editors have recommended. Also based on the reviews, try to find out which is the last generation of GPU for the time being. Right now the last generation high end GPU from NVIDIA is the GTX 280. We couldn’t find a 280 GTX card below $250, but we did find one for $260 so the prices are dropping.

We recommend you to go with the next to last generation cards like the GeForce 9800GTX or 9800GX2 (dual onboard GPU) and the ATI HD 3850 and 4870. They will offer you a great performance/price ratio.

Advanced graphic cards
Obtaining maximal performance and resolution may lead you to spend $400 and above on a high end graphics cards. This is for real gamers who need that extra FPS rate and resolution to perform optimally. You should look for dual GPU solutions, either onboard dual GPUs or using SLI or Crossfire technology (two physically separated graphics cards working together).

The 3870 X2 with 1GB RAM from ATI is a good alternative and is somewhat cheaper than the 4870 X2 which naturally gives some extra percents of performance. From NVIDIA you should take a look at the GTX 280 and 9800GX2.

Nvidia has been recognized as the leader in visual computing technologies. The firm has created and marketed an array of products for lines like Quadro, GeForce, and Tesla. The Nvidia driver download is an easy process, which can be done by anyone with basic knowledge about the computer. All of these have been used for industrial designs, gaming, financial models, broadcast purposes and other related uses. It can happen that the Nvidia hardware on the computer could be experiencing trouble, because of the driver being outdated.

About the Nvidia drivers:

The Nvidia device drivers are vital for the apt functioning of your computer. These are an agglomeration of files, which enable effective communication between your hard drive and the operating systems of the printer. There is requirement for a new Nvidia driver downloads if-

The driver is outdated or has not been updated for a whileThe driver has been corrupted of infiltratedYou have changed your computer or printer

In these cases the driver would not be able to function well with your computer and the program would freeze up each time you make an attempt to use the device. The computer screen may also crash when you try to use the outdated device.

How can you make this problem worse?

There are a number of ways through which you can make this problem worse and these include-

Ignoring the error and restarting your computer each timeToo many errors would result in poor performance and application freezesNot following apt instructions during downloadingNot changing your driver regularly because it may appear to be a daunting taskUsing a driver that does not match your system specifications, especially if bought from the wrong siteComplete the Nvidia driver download properly

Convenience for downloads”

These days you can access Nvidia driver download through development of various software for driver updates. Hence, most of the processes here are carried out via software. The entire process of scanning, downloading and installation takes a few minutes. You just need to choose an apt driver from the list of updated drivers, but make sure that you avoid downloading from malicious sites, or even the wrong product.

There are an array of articles related to DriverCure and Driver detective at our website. These can help you get expert opinions and guidance on issues related to downloading and troubleshooting of drivers.

When this card makes it through POST, it is really good. I have had all settings on high in a new game demo yet to be released at the highest resolution possible and it was just fine.

The fan never needed to go higher than 50 percent of speed, and it is very quiet up to 65 percent or so. I used ATI Catalyst to auto-tune the over clocking and it went from factory over clock at 870 megahertz to 980 megahertz all while with memory at 1,050 megahertz. Could probably go higher but it is definitely enough for right now.

The first original time that I powered this up the fan went to 100 percent, sounding like a jet poised to take off. And the screen was blank, though POST beeps sounded normal. Thought maybe my motherboard did not appreciate the change to ATI so I shelled out 40 five dollars for a cheap nVidia card.

Installed it, and it booted first time. Switching the 4890 back in, it is now working for some reason. Subsequent reboots worked about 50 percent of the time so I finally removed it and sent it to Sapphire. So now I am without the card for a couple of weeks due to poor quality control.

I have looked elsewhere and noted that other people have been seeing the same problem with this such as the blank screen on boot.

Perhaps there was a bad batch and I was the unlucky one. Really annoying as I am out 45 dollar for a replacement card plus the postage to send it to the Sapphire service location.

It seems it is not my motherboards fault as my friend’s Sapphire 4850 worked like a champ.

I can overlook a defective unit if it’s an isolated situation, but having seen others report the same issue. I rate it low when it does not work, and five stars when it decides it does want to work.

If you’re reading Dell Vostro 1320 reviews, you probably want to know whether or not this notebook is worth buying. If you’re looking for a system that offers remote management options and integrated video for communication, then the 1320 is definitely something you should consider buying. Here are just some of the many reasons why this notebook is great:

Despite the ratification of OpenCL as a standard may have changed significantly in the scenario of GPGPU applications, Nvidia has no intention of abandoning Cuda, a platform on which it has invested and will continue to invest.

The American company has decided to present a new version, for now beta, release 2.1, which introduces support for Windows Vista, for products Tesla and a 32-bit debugger can run on RedHat Enterprise Linux 5.x. It also added support for VisualStudio 2008 on Windows XP. According to the company were included in the new API can work properly with Direct3D 9 and Direct3D 10, this must be added a number of improvements in interoperability with OpenGL in addition to support for many of the recent Linux distributions.

Nvidia, as AMD has recently announced that developers can use the SDK to create applications based on OpenCL able to exploit the GPU. The Californian company had, the beginning of the year, also announced the forthcoming introduction of a platform capable of Cuda function properly on x86 systems: the launch was subsequently postponed to the end of 2008, and now, according to many sources, such platform may not ever arrive. In this scenario it should be added to Intel’s Larrabee, a product that American society has long since dropped the curtain, preferring to work behind the scenes. It predicts a hot and intense in 2009 as regards the reality of the applications with accelerated graphics card.
