Hah your rig is near identical to mine, just a generation behind. I recently upgraded my hawk and couldnt bring myself to move away from MSI gear. I was told a jump to a 670 wouldnt be that noticable so should get a 680, but that was just the store owner trying to make a buck. I got a 670 Power edition, which is about 5% slower than a 680. Good value right there. My 3dMark11 score went from approx 6000 to approx 9000. Decent gain right there. The twin frozr 4 is also quieter than the 3.
