I don't know about Wolfenstein, but it runs Deus Ex and Unreal Tournament BEAUTIFULLY, with NO slowdown whatsoever. I turn all settings to maximum with no problems at all.
It runs Myth III extremely well, as fast or faster than any other top-of-the-line PC (OK, it crashed on the Ultimate Insane Dwarf Killing Spree level (Myth III players know what I mean) since it has around 160 fully textured units in full 3D, but lowering the detail levels a notch helped that.
Summoner works great.
Oni works great (but then again, I'm not surprised)
Haven't tried Alice, but it should be fine.
Get thisSTARCRAFT runs REALLY WELL!
lol
Giants runs amazingly well, with all settings all the way up (WOW)
Quake III is incredible (but then again, it was fine on my old ATI Rage 128, which is why I don't understand why people use it as a benchmarking test... it runs at 100fps on a Pentium 200 with an original Intel Integrated Video card (and yes, I've tried it)...)
And that's about all the games I've tried so far.
