I've got 512 in this thing and I'm comfortable with X. I actually use Final Cut Pro on it and it runs great. I play Myth in Classic and it's glass smooth. I still hate web browsing in X and window resizing, but it's not much worse than my G4 450, so the iMac holds its own.
I would get more RAM and jump on board the X bandwagon. For the casual user, X on an iMac is a really nice visual and interface experience.
