Notes

Under the greater demands of 2560x1600, the situation improves a little for Quad SLI, Quake 4 is now showing an advantage of nearly 30% over GeForce 7900 GTX SLI, while the Quad card outruns 7900 GTX SLI by 14% in F.E.A.R.

All isn’t rosy for GeForce 7900 GX2 Quad however, as everywhere else the SLI and CrossFire rigs are still delivering better performance. Again, part of this is due to the Quad cards lower clocks, and extra driver overhead may be playing a role. It also looks like the Quad card may be falling back to 2-way SLI in some tests.

In order to really see where a Quad SLI rig shines, you’ve got to turn the settings up a little higher. Let’s crank the AA up to 8x!
