Help me build: My WoW computer

[worshipme]

Just want to run WoW perfectly, is the videocard I picked good enough?
If not something from newegg something from the best buy sight thats around 200 or so, maby a bit more. My discount is quite random

I would go with a different mobo, this Biostar. It's cheaper and it's a much better OC'ing board.
The HD 4670 will be more than enough to run WOW perfectly and quite a few other games as well.
PSU, I think you'd much prefer modular and 500W is more than sufficient.
