Still works fine. WoW is damn old, and most things that can actually benefit from four cores need parallelism more than brute per-core power. Really, modern CPUs are overpowered for most things that end up being done with them even more generally.
Exactly. When I stopped actively multiboxing for a while I had the VAST potential of my CPU just sitting and wasting away from lack of use. (So I started folding)

Save your bucks on w7 and video card for a new system at a later time.
Indeed. While W7 is snappier and altogether better, it doesn't mean you have to rush to get it (Unless of course you're a student and can get it for twenty dollars. )
