Thanks for the advice. I forgot to include the cost of Windows in the OP so I don't think I can afford a better GPU at the moment.
You should seriously consider websites other than microcenter. Despite their excellent deals on CPU and Mobo, the other stuff is slightly higher in price relative to newegg, tigerdirect and amazon. In addition, you will have to pay sales tax in most states plus the gas cost of driving there (microcenter is far enough from me that it wasn't much savings after that).
