Actually go for a 955+better GPU (HD6870/6950 or GTX560/570) in your case.
However nice the SBs are, with a 6850 its not really going to shine.
My parents are now going to buy me 2 computers:
1. from HP (my main one) w/ 2600k. In all honesty I REALLY want an AMD processor just cause my first comp was an AMD, but i'm willing for change
2. Parts from newegg for me to build my own
