Notes

At 16x12, F.E.A.R. is the only title that takes advantage of our Quad setup. As you can see, everywhere else the GeForce 7900 GX2 Quad is outgunned by GeForce 7900 GTX SLI and Radeon X1900 XTX CrossFire (with the exception of Quake 4), in fact the 7900 GX2 Quad barely outpaces the single GeForce 7950 GX2: in fact performance is tied in Quake 4 and Half-Life 2: Lost Coast. Driver overhead may be playing a bit of a role here, but it’s surprising to see nevertheless. We weren’t able to complete our tests with the CrossFire rig in Far Cry at 1600x1200 for some reason.
