I'd like to see it too. I can run WoW on my macbook at ~35 fps out on my own. However, I'd think that even integrated graphics should be able to do better than that.
I've read that the x3100 performs the best in windows XP...I'm tempted to try it. Hopefully apple or somebody will release some nice drivers for it so we can get some decent performance.
That said, I didn't buy this thing to be a gaming machine, but one can hope
