The Low-down On Graphics Cards

A graphics cards is perhaps the most important component of your computer. It is the reason that you perceive the video output on your screen instead of binary numbers. Since you have just bought your computer your computer may not be loaded with a dedicated graphics driver, rather a built-in graphics chip meant to perform al the necessities.

A built in graphics card usually shares resources from a computers own processor. A dedicated graphics card on the other hand, comes with its own dedicated resources like its own processing memory and image processing capabilities that not only free system resources but also allow you to accomplish heavy graphics requiring tasks like video editing, an animation or playing 3d games.

A graphics card usually consists of a dedicated graphics processor, memory chip, and a RAMDAC for display output. It may even offer value added capabilities like video capture, TV output, SLI or other such options.

While considering purchase of a graphics card it would be wise to consider you requirements, a simple low-cost integrated graphics card will suffice if you require 2dimage rendering or similar 2d usages, you will need a high end graphics card if your intended use is for 3d rendering, animation or high end games like first person shooter or flight simulators.

There is a substantial difference in both the cost as well as the performance of a high end and low end graphics card. Rendering a 3d image is very much like lighting a stage, reflections and refractions from surfaces as well as their relative textures must be taken into consideration and the tasks require massive amounts of memory, a graphics card efficiently handles any such tasks with its own dedicated processor and 3d rendering capabilities.

Most of the modern graphics cards also come with small microchips called GPSs Graphic Processing Units that provide algorithms and memory to better process complex images, efficiently reducing the workload on a computers processing unit. Different graphics cards come with different processing capabilities. You would like to consider a number of things before buying a graphics cards.

Things like a processors clock speed, memory size, RAMDAC and fill rate are of primary importance in determining how efficient a graphics card may prove. It also good to know that though you may find graphics cards from a number of vendors, essentially all of them usually feature its central chip made by either ATI or NVIDIA. Cards that use the same chip have roughly same capabilities, though they may offer other value added features like over clocking or higher memory cards

would i be better off with a new graphics card or SLI?

Should i buy a new graphics card which would be really expensive, or get another 8800 GTS 320 mb graphics card for about $100. My computer has 3 SLI slots but one of them is a different speed or something, anyway thanks in advance!

In your case I believe it would be better to buy a new one and leave the SLI alone for now. I doubt you would even get that much of a boost from buying an additional 8800 GTS. The new cards are very good!

Practice rock-paper-scissors alone with this DIY game glove
Rock-paper-scissors, I imagine, was one of those games created when people were looking for fun and competition but lacked any kind equipment (or even a deck of cards for that) matter to play a game. But as simple as a game rock-paper-scissors is, however, some people take the game very seriously and it is even considered a sport [...]
