Fools with older cpu´s and mobo´s - save money and only buy a good OC´ed gtx 970 or 980 first.
Game runs fucking fine cranked nearly to the max on a 955 phenom II, 8 gigs of ram and an EXTERNAL USB 2 hdd!
The Samsung 850 pro I ordered will help me get rid of the fps issues caused by the slow data rate from the hdd.
Only played SP so far, never was an open world fan, but this game...jesus...best open world game ever maybe.
Not a single crash in 25 hours ingame. Quite the opposite of gta 4 (which I never got into).
