I think its the 6080fx or something like that. I'm going to stick w/ desktop. Crossfire x is only for benching. I don't game that much. I'm a console gamer. I'm deciding what I'm going to do. I want to sell my quad and go yorkie w/ the asus maximus II, 4gb dominators and try out crossfire x. Worse case scenario I sell the extra 3870. Thats my plans right now. Looking at 2 weeks to get it all done. So far I have the tagan bz700w,hdd and lian li case for the build and thats all lol.
