Hello Guys, Got this current gpu at the moment: Sapphire 7970 OC+Boost http://www.sapphiretech.com/presentation/product/?cid=1&gid=3&sgid=1157&pid=1481&psn=&lid=1&leg=0 Was wondering if i add another card just like that(xfire), might encounter the nightmare called "Microstutter"? I'd like to play games at the rate of 120mhz(no 3d-just 2d) My current Monitor (Sammy 950D) will be the main monitor, the other 2 will be just as an extended desktop. Not planning to Oc the card at all ultill the MS is being mitigated. Finally, my mobo is an asrock z77 fatality pro. I Believe that if i run xfire on this mobo, i will be having a pcie lane of 8x-8x, which might not slow down the game speed. Thanks for your help.
