I've got two 6950s in crossfire and haven't had any issues yet. Runs BC2 great at 2560x1440.

Can't complain about the i7 either, seems to run stable at 4.5 GHz with the d14 cooler. Although if you are just gaming I would recommend the i5, because in most games it runs about the sam as the i7.

Also, SSDs are a must these days. Once you have one you will never turn back.
