Test Setup
The NVIDIA nForce4 SLI X16 chipset fully supports all AMD Athlon 64 processors in both stock and overclocked conditions.
We tested our 7900GTX video cards using NVIDIA 84.21 WHQL drivers and ATI X1900XT cards with Catalyst 6.3 to provide the latest video performance results. Resolution in all benchmarks is 1280x1024x32 unless SLI is enabled. Resolution in SLI and comparative X1900XT CrossFire benchmarks is 1600x1200x32 with 4XAA and 8xAF where applicable. 3DMark03/05 benchmarks use a "Standard Score" setup at the 1024x768 video resolution while 3DMark06 uses the "Standard Score" setting of 1280x1024.

Just FYI, I've sent Gary a message to check the FEAR and COD2 CF numbers. They seem a bit low to me, but I haven't personally tested a CF system so I can't say for sure. Gary will most likely be on in a couple hours to comment, once he gets out of bed. Which is where I need to go now....Take care,

It looks like the current FEAR and COD2 scores for Crossfire are correct, in that CF doesn't work fully right now. Unlike SLI where profiles can be manually force, CF mostly works or not. Just in case anyone was wondering. :)
