as mentioned i'd pay the bit extra for the i5 750 quad core.
whats the idea behind the 160gb 5400rpm hard drive ?
rest looks fine
Just get rid of the 160GB drive. At 5400rmp it's only going to slow down the performance of the PC! Install the OS on the 1TB and scrap the 160GB, you'll get better performance.
Then spend the saved money upgrading to an i5 750 and perhaps some 1600MHz RAM for increased overclocking potential.
