I'm going to suggest something a little different:
a8-3870K Llano + Gigabyte A75 motherboard: $159.98
http://www.newegg.com/Product/ComboDealDetails.aspx?ItemList=Combo.951798
unlocked processor and good mobo.
Rosewill Redbone + Rosewill Green 450W PSU: $74.98
http://www.newegg.com/Product/ComboDealDetails.aspx?ItemList=Combo.976469
good case, reliable PSU - the Rosewill Green PSUs have been reviewed as pretty reliable.
Hyper 212+ Cooler: $29.99 w/ $10 rebate
http://www.newegg.com/Product/Product.aspx?Item=N82E16835103065
yes, it will fit in the case if you remove the side intake shroud.
Pareema 8 GB DDR3-16000 $40.99
http://www.newegg.com/Product/Product.aspx?Item=N82E16820576013
reliable so far, even if Pareema is a fairly new company.
Sapphire HD 6670 DDR5: $89.99 w/ $15 rebate
http://www.newegg.com/Product/Product.aspx?Item=N82E16814102958
in hybrid crossfire, this approaches a 6770 in ability for Direct X 11 titles.
Seagate Baracuda 1 TB drive: $99.99
http://www.newegg.com/Product/Product.aspx?Item=N82E16822148840
total $495.52
