EVGA partner with nVidia to release a line of several graphics cards with chipsets manufactured by nVidia. When you decide upon getting a graphics card, you first must look at the interface to see if it is compatible with your computer. CPU clock speed, the quantity of VRAM, and the front-side ports for monitor attachment, all affect the performance and compatibility of the graphics card and your computer.
Input Ports
The 7800 GT chipset included with EVGA has two ports for DVI cables and one port for S-Video, which supports two monitors and an S-Video TV set. If your monitor has a VGA cable, EVGA includes a DVI-to-VGA adapter to allow your monitor to connect to it without needing to support a DVI interface. This adapter simply converts VGA to analog DVI, allowing for high resolutions of up to 2048x1536 pixels at an 85 Hz frequency.
Interface
EVGA's 7800 GT card requires that your computer have one unoccupied PCI Express x16 slot dedicated for video. This slot looks longer than the other slots on a standard ATX motherboard and has a small plastic lever at the back to fix the card in place. If you do not have such a slot on your computer, you cannot use this graphics card unless you install a motherboard on your computer with PCI Express slots.
GPU Clock Speed
The graphic processing unit in a graphics card acts as a supplementary processing agent which keeps the number crunching out of the computer's main CPU when it comes to graphics. Without this unit, all graphical rendering would have to be done by the computer's CPU which does not have the optimization necessary to perform advanced rendering. A 7800 GT card can do 400 million operations per second (400 MHz).
RAM Quantity and Technology
Your RAM holds much importance when storing graphical polygons in the middle of games or while you design something through a graphical editor, such as a 3-D studio application. The more RAM you have, the more seamlessly your gameplay or graphic editing experience will be. EVGA's 7800 GT card has 512 MB of GDDR3 memory, giving you plenty of breathing room, as most applications as of 2010 demand less memory than this to function well. The term "GDDR3" stands for the kind of technology your memory uses, which primarily can tell you what kind of speed your card has while seeking through the memory and transferring objects.
Microsoft Compatibility
Although you virtually may run a graphics card in any operating system, this card works better on some than others. The EVGA 7800 GT graphics card boasts compatibility with Windows 7. It also supports Windows Vista and 7's "Aero" interface which many Windows users find attractive. The smooth glass effects of Aero make work on a Windows computer more fluid and graphically aesthetic.
