also a 3540 if you have a micro cneter near you is 150.00. also on the power supply cosair can be bought at a good price and there a good power supply too. you dont want to go cheap on a power supply and have it take out your gaming rig.
if the funds are there i toss in a small 128g ssd as a boot drive. i got one on new egg for under 100.00http://www.newegg.com/Product/Product.aspx?Item=N82E16820227791
has 70.00 rebate right now. I would also look into the 7000 and 600 line of cards..they newer and use less power then the older cheaper cards.
