Prey is one of the few games we’ve checked out so far where the GeForce 7950 quad-SLI can show its worth. It delivers a performance boost of 70% in 1920x1200! That’s an achievement for a quad-GPU graphics subsystem whose scalability is a priori worse than that of a dual-GPU one. However, the Radeon X1950 XTX CrossFire is slower than the leader by only 15-17% in that resolution and almost rivals Nvidia’s subsystem in the lower resolutions while being cheaper and providing a better-looking image.
The GeForce 7950 GX quad-SLI looks better than the competitor in SLI AA 8x/Super AA 8x mode because it provides a comfortable frame rate in 1600x1200 and, with accidental slowdowns, in 1920x1200. ATI’s tandem delivers an acceptable speed in 1280x1024 only.
The rivals exchange places, but their speeds are too low here for you to play the game normally.
