Well, I returned one of the 7970's and my original one I had to RMA. The crossfire wasn't working out too well with games and I got sick of troubleshooting. I also got a set of CORSAIR Dominator Platinum 16GB (4 x 4GB) 240-Pin DDR3 SDRAM DDR3 2133 Desktop Memory Model CMD16GX3M4A2133C9. The problem is, is i cant get a stable OC on the RAM at 2133 and anything on my 3930K over 4.0. It could be the Gigabyte X79 UP4 or my lack of knowledge with a Gigabyte board.
Here is my now with a MSI 5450
