This is a good build, I suggest it for you, wiz.
I like to suggest to people on a budget to buy from eBay. The only problem is, most people on a budget don't have enough experience with computers to know how to make sure the product they received is *fully* operational. Not to mention there's only certain parts and certain brands that you should be buying through eBay (RMA without proof of purchase).
Cool thing is, if you know your way around, you can end up getting a 2012 (year) $700 rig (mobo/processor/ram/etc) for $400 and get something like a lightly used GTX 670 for $150. $550 paid for a $1100 rig that will last a few years. Not too bad. Not to mention the GPU will play most games on Ultra @ 1080p. Only problem you may run into would be future games utilizing more cores, but I don't think it will be much of a problem.
Just my 2 cents.
