I didn't actually get to get into gaming until early today. I'm sure after a good reformat the performance will be better yet. I'll take care of that tomorrow.
But yes, Doom3, Far Cry, and CSS all run brilliantly. This system kills my desktop computer when it comes to playing games. That and this thing is what, 100watts? It's much more energy efficient, quiet, and warm not hot. The keyboard is a little warm and when the GPU gets too hot the right rear fan spins up which causes the left one to slow down. They trade the cooling load back and forth. Bottom line is that you won't feel stupid playing games in public and the same goes for DVD's and CD's.
I've noticed my LG LCD, despite its sparkles, likes to push the color red. Not a big deal. I'll take red over no yellow which annoyed me about my sony.
EDIT: And that internal pic posted above will confirm what I said about the fans. Do note that when in Doom 3 I noticed both fans were sharing the load but neither spinning at full speed (I haven't had the system do that yet). In UT2004 more speed was on the left rear fan.
