SLI Boosts Crysis About 20% Performance
From the Crysis built-in GPU benchmark we can see, 8800GTX SLI have 22.70%(average) more boost than the single card sultion.

Our Test bed:
Mobo: Asustek P5N32-E SLI(680i SLI)
CPU: QX6850
Graphic card: Leadtek 8800GTX SLI
Memory: DDR2-800 4-4-4-10-1T
OS: Microsoft Windows Vista â„¢ Ultimate 32bit Service Pack1, v.275
Driver: Forceware 169.04Beta
This score is close to the 3DMark06(defult) test score. This means under DX10 SLI really have some boost for Crysis, and proofs that those talking “SLI have no improvement on Crysis” is not a right comment for SLI.
EA may patch Crysis in Nov. 16 (when the game offically begin selling) and of course NV’s Forceware will continue to opimize. SLI only have 2x% boost is really bad in TWIMTBP games. Of course, We hope there will be a better improvement in the final release.
