Can run BF3 on all high flawlessly, haven't tried ultra yet b/c I am lazy.
CS Source, ... lol ... 299-300 FPS all the time on most maps, maybe low 100s on bad maps with lots of stuff going on
That said, if I had to buy today a new gaming rig with my own money, I would do a 2600K/GTX570 (or 580) build with SSD as boot/apps drive.
