Uh, that's total bull how all the butthurt people are attributing the difference to factors other than the video card.

First of all, the video card will overrule any error that the system will induce into the benchmark. It has been conclusively proven that memory tweaking does not significantly affect results, and even with the latest Anand benches for CPUs, all of these are quad cores that are basically the same architecture.

Second of all, the nvidia cards are using 'superior' CPUs. If anything, this makes an even bigger case for the 4890.

Third, the 'win' between the GTX285 and the 4890 is extremely close. I don't see why people can't stomach the fact that an OC'd 4890 competes extremely close to a GTX285, which has already been shown in the benchmarks.
