Alright, it installed without messing around it. The Windows Experience Index put Graphics at 4.3 and Gaming Graphics at 3.9
That is an improvement from 1.0, but I tried running Anarchy Online, the game I frequent, and everything lags badly and everything has sharp edges, even when it shouldn't. I am happy it works now, but if this is gonna be a step down I'm going to want to get back to my Vista setup as fast as possible
Edit: I restarted Anarchy Online, and got an error message: "Could not find the selected display driver/device combination! Using default!"
Probably why that happened (it still had the problem this second run)
