It was my first CF attempt. But the results were simply horrible in all games ( Crysis 2, DiRT 3, Max Payne 3, F1 2011) EXCEPT DiRT Showdown. 1)Dirt Showdown Singe card 36 Avg CFX 59 2)Crysis 2 Single card 50 CFX Avg 35-40 3)F1 2011 Single - 50 CFX 47~ 4)Dirt 3 Single - 47 CFX 44 AMD x6 1055T @ 3.7 8gb Vengeance MSI - 890GX - GM65 CARD 1- 1GB HIS 6870(Stock Clock)@8x CARD -2 1GB Sapphire 6870(Stock Clock) @8x CM GX650 PSU Top video card to Yamaha 467 AVR Via HMDI >> AVR to 55" TV(1080p) via HDMI I've tried 12.2 / 12.7 Fresh OS install on different HDD.
