Spending around $700 on it, can't really spend any more than that. I will be using it for WoW, SC2, as well as some other slightly more system intensive games (probably not any fps), and audio recording/engineering (pro tools, etc).
These are the parts I have picked out; I've never built a computer before so I just want to verify that the parts will work flawlessly with each other, and that I'm not buying anything that has way more or less than I need/best bang for my buck
Hmm, I don't see anything hugely wrong, but you may want to reconsider that PSU. And I'm no pro with video cards but if this machine is going to be for gaming this is not the place you want to be saving money. I suggest EVGA GeForce GTX570 1024 MB which is probably about double the price as your 460 (factory superclocked another $30-50) but is currently 'out performing' the 480's and will probably serve you longer than the 460 making it cheaper in the long run.
But like I said I'm no authority on building computers, so someone else may be able to give more insightful feedback. I myself would actually like to know if this could handle WoW and SCII on max settings easily.
The GTX570 is unfortunately well out of my budget, the 460 superclocked was pushing is about pushing me to my limit budget-wise. Would downgrading some other parts for a better video card be worth it? I remember reading the tom's hardware report for benchmark tests for cataclysm, and from all they tested the GTX460 gave the best bang for the buck.
