4870 Crossfire overkill for 1680x1050?

[Dr_Fartypants]

I would dearly love to know what folk out there do to get the gains they are stating.

Try forcing it to use multi-GPU, rather than letting it select automatically.

To your crysis shortcut, add: +r_MultiGPU 1


eg, for the default install location, right click on the shortcut, go to properties, and change to:

C:\Program Files\Electronic Arts\Crytek\Crysis\Bin32\Crysis.exe +r_MultiGPU 1


Note though that proper multi-GPU support was not added until patch 1.1 (I think...), so if you're running just the demo version for the benchmark you won't see any improvement. I think there is a box in the benchmarking tool where you can add the r_MultiGPU=1 command also.

Thanks for that. So do you think the 2 cards is a worthwhile investment at my screen res then? Ignore Crysis, that's just a poorly coded game.

For all things other than Crysis (and I will try the aforementioned suggestion by Fartypants later tonight to see if I can get some 2 card gains), I have been really impressed with my 2 x 4850 combo.

I'm seeing huge gains in GRID, UT3, COD4 and BF2.

Can't really comment much outside of this arena though so it's a qualified opinion.
