Gaming results
Far Cry and Quake 4 are tested with a single graphics card and Splinter Cell: Chaos Theory is run with multi-GPU, be it CrossFire or SLI.
Likewise, in games running at resolutions where the CPU is the limiting factor, the Athlon FX-62 simply can't match Intel's Core 2 Duo X6800. It can only deliver three quarters of the frame rate in Far Cry at 1,024 x 768.
GeForce 7900 GTX is faster than Radeon X1900 XTX in the OpenGL-based Quake 4 test, evidently. Core 2 Extreme power lifts the i975X board clear.
At really high resolutions, however, the CPU was no longer the limiting factor, and the results are pretty indistinguishable across the two platforms that use CrossFired ATI cards. GeForce SLI lags a little behind.
