I actually have 6770 and it plays the game great imho.. i play at minimum 80fps @ 1920 res in a 32" tv.. currently have i5 3570k with 4.2ghz (with OC Genie, haven’t got the time to OC it manually
) and 16gb ram if it makes sense.. have no idea how much the fps will drop when i play in WvW since i just got the game yesterday.
