Total ~$700 - $40 MIR's = ~$660!! Over budget, but not sure if this works for you or not. Could adjust the GPU some, depending on what you want to do. I probably wouldn't go below a 4670, 4830, 9600gso/gt, 9800gt, if you going to be any higher end games. It's going to depend on what your resolution that you'd be playing at and what games your going to be running.
