agree, you might eventually think about getting a closed loop CPU cooler like corsair h70 or some huge air cooler like the silver arrow. Your huge motherboard has huge voltage regulation and OC potential.
Agree with xtreme about the graphics as well. Playing any battlefield 3 or other graphics intensive stuff? 6950 or 560ti (either one) would be great if you can work it somehow.
If you dont feel like waiting on a graphics return, just wait for AMD's next generation of 28nm graphics cards. If you find the 6870 to be inadequate, you can OC the mess out of some cheap 28nm card next year or earlier and sell the older card.
