I got my new PSU, and it worked.
Graphics look phenominal now, atleast when compared to how they looked before.
Though, I think there may
be some bottlenecking going on. It first began running WoW on 90 FPS, and after about an hour it went down to 50 FPS average. There is also the occassional skip. I'm thinking of upgrading to 4GB of RAM (even though I've XP and probably don't need that much).
Still, it's wonderful.
