Look at my sig, then copycat it! LOL I love my PC! My setup falls around your price range, but I already had a monitor(I just use my 42" LCD TV). Although I will be upgrading to a dual Video card setup, the single 610 with 1 Gig works great, I can run Call of Duty MW3 and BF3 with full graphics and options
.
Check Microcenter for prices. They've got some killer deals.
Good luck!
