Any number of folks (me included) have zero issues with that CPU, so ignore CPU for now. (The exception is if you haven't yet set your wows up to use either all 4 cores or dedicated 2 to the first two and 3 to the second two cores. If you leave 'em at defaults, the system will only use the first two cores.)
QFT.

I would say, get a 4870, the PSU to juice it up, and a good (can be small in volume) SSD to run your WoW folder from.
