3D Performance
Half Life 2: Episode 1
Quad SLI doesn't buy us much in our HL2: Episode 1 benchmark, and 7950 GTX is outclassed by 7900 GTX SLI. However 7950 in general, be it eVGA or reference, is the fastest single board in our testing by some margin. eVGA's example bests the reference hardware by useful amounts, although less than theoretical maximum simply because of resolution. Feeding 4.1 megapixels at high fps takes masses of bandwidth.
Quake 4
Quad SLI gives us nothing in Quake 4 at 1920x1200, when we hit apparent CPU limitations. But up the pixel count by 70% and the graphics hardware comes back in to play. Quad SLI then buys you a chunk of performance, and you can also see the eVGA Black Pearl in single-board config keeping pace with 7900 GTX SLI, despite a clock deficit, at 2560x1600.
F.E.A.R.
Quad SLI is a win in F.E.A.R, and at 2560x1600 single GX2s beat 7900 GTX SLI, which we weren't honestly expecting. Driver bug maybe, but currently repeatable in our particular FRAPS test.
Oblivion
Quad isn't a win in Oblivion, highlighting one of the aspects of multi-GPU configurations, and the eVGA board has a healthy increase over the reference hardware, to the tune of almost its clock increases, showing scaling. 7900 GTX SLI remains the best choice for high-res, high-IQ Oblivion, from the hardware on test of course.
