TimeShift
This game may be a bizarrely derivative remix of Half-Life 2 and F.E.A.R., but's it's a guilty-pleasure delight for FPS enthusiasts that has a very "action-arcade" kind of feel to it. Like most of the other games, we played this one manually and recorded frame rates with FRAPS. We had all of the in-game quality settings maxed out here, save for "Projected Shadows," since that feature only works on Nvidia cards.

This time, the GTS 512 even outdoes the 8800 GTX in single-card performance, though not in SLI. The GTS 640MB just isn't as fast, which is one reason I take issue with the naming of the GTS 512. As ever, though, the 8800 GT OC card shadows the GTS 512 closely.

The Radeon CrossFire scores look pretty good here, but I should mention that, although we were able to test, we encountered annoying visual artifacts (the screen was flashing) while playing on the CrossFire rigs, even with AMD's latest drivers.

BioShock
We tested this game with FRAPS, just like we did the UT3 demo. BioShock's default settings in DirectX 10 are already very high quality, so we didn't tinker with them much. We just set the display res to 2560x1600 and went to town. In this case, I was trying to take down a Big Daddy, a generally unsuccessful effort.

The trends we've seen before continue unabated here, mercilessly offering me very little to write about. SLI seems to be no help at all in this game for the GTS 512. None of the GeForce cards gain much from SLI in BioShock, but most of them do gain some. We're using slightly newer drivers on the GTS 512, which may explain the scaling difference.
