Motherboard: Your not OCing so there is no point getting the Asus P8P67, the Asrock Extreme4 P67 would save you bout 30$. Plus it's basically the same board. The Asrock can OC just as well, your not using that though so it doesn't matter.
CPU: Drop down to the i5 2500. The 2500 still beats out the i7 950 and is cheaper by quite a bit. Plus you really don't need multi-thread since your only playing games. The 2500 is enough and will save you about 100$.
