Thanks guys. The 600 people laid off is making me rethink this a bit. I'm probably going to wait a few months to see further developments with WoW. I'm not saying I'm expecting it to die or anything, but if they keep losing subs not sure I want to blow so much money on a game whose future is uncertain.
In the meantime I might be able to buy cheaper components, I think there's some new generations coming up soon.
