Bump:
I've tested it out with almost all my graphically-intense games (stuff like Left 4 Dead 2, TrackMania United and Fallout 3), and it ran it all perfectly, at high (if not max) settings.
Only issue is, in Fallout 3, framerates turn horrible after a while. I think it has something to do with the game itself (being as broken and glitchy as it is), because after I start getting lower framerates, if I go to a place where before I had a higher framerate (say outside of Megaton), I still have horrible framerates.
But, so far, I'm generally impressed with this thing when it comes to gaming.
