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.

Strange thing is when I Run my 22" LG (1650 x 1050) to Top Video card via DVI, No other output in use, all games scale(Except F1, but that seems to be a game issue) Any help would be greaty appreciated More about : 6870 faxfan July 10, 2012 10:07:01 AM Have you monitored the cards to see if the GPU is being utilised? GPU-Z and enable logging on the "Sensors" tab (make sure you select different cards on the first tab). m 0 l sl4y3r July 11, 2012 4:11:04 PM The GPU is being used some game 99% on Each GPU , some 100 on 1 and 50~60 on the other. But why does it scale only over DVI and not when I have it on HDMI to My AVR ?(AVR to TV) m 0 l Can't find your answer ? Ask !
