I second ET3D to test drive this sort of machines for casual gaming.
I for one would love to see how WoW or DDO would run on it, I know I ran DDO on a GMA945 with a bit of lag normal gameplay, and a lot of it in big areas. On the other hand, how the n330 works on java games, like facebook games, with an N270 some games lagged hard, even on an a64 5000+ have seen them lag when too many objects are on screen.
The idea ET3D gave was not for hard gamers, but the casual you can play on the net maybe.
@Fastvince: I doubt we will have USB 3.0 as new standard in 6 months, maybe a little more time to come.
