CrossFire is the new dual graphics card system from ATI. It offers remarkable image quality improvements for game play and 3-D work.
People who demand the absolute highest levels of performance have tried every possible combination of CPU, motherboard, and graphics card in their gaming rigs. While results have often been excellent, there are those who are still unsatisfied.
In an effort to push beyond previous limitations of the PC, ATI has turned to the technology it uses in commercial flight simulators, creating a double card system. The new system can deliver up to a 100 percent increase in frame rates, and an 80 percent improvement in overall performance at high resolution settings.
For the gamer, it means dazzling image quality, while never again having to lower screen resolution in order to play a game.
You may be asking “What do I need to set up my own CrossFire rig?” The only necessities are a CrossFire ready motherboard, and a pair of ATI Radeon graphics cards, or other compatible GPU’s.
In the best of all possible worlds, you’d build your system from the ground up, starting with the fastest CPU you could get your hands on. Mount it on a super motherboard, such as the Intel 975X Express, the Asus P5B, or the Gigabyte 965P-DQ6, all of which are CrossFire ready. Get top of the line ATI Radeon cards, and you’ll be in business.
An additional thought: get a big power supply, 500 watts or greater. The two cards and CPU could easily use 300 watts by themselves.
