3DMark05 at default resolution (1024x768) is not the benchmark you want to use for comparing SLI/CF efficiency. Its 99% CPU bound w/ 3.5GHz FX60 and 750/850 clocked X1900CF. You can see that GT1 and 2 are basically the same with both SLI and CF and only the most GPU dependent GT3 shows a small difference (at lower CPU clock even that would be equal). Overclocking the cards at that point gives zero improvement. You'd need higher CPU speed to see the benefit of increased video speed.Quote:
My opinion,
i don't think this is impressive at al
actually i can say these crosfire results are bad when you compare it with the efficiency of sli..
GTX512-->9.6K
XTX--->11.5K
2*GTX512-->19.2K
2*XTX---->19.5K
oh yeah hats off for ati and crossfire they sure rule
If you want to compare them with 3DMark05 I suggest running it at (at least) 1600x1200 4AA 8AF. Even then GT1 and 2 are highly CPU bound.
