Hey there everyone, needing a few pointers here. My budget is rather low at the moment, I -really- shouldn't go over $600. I put together this bit for about 550 bucks, will it work?

It's pretty bad to be honest, you can get MUCH better when building yourself.
Don't expect any great performance in WoW.

Can you suggest anything better then? I'm willing to build myself, I just don't want to go over my budget because money is hard to come by these days. I have another list which I thought could work, but again I'm not sure about this sort of thing.
