I am using hd6870 straight with i7 4770k without any problem. No more swap required.When Mountain Lion came out, the 68XX cards were having serious issues. If your CPU didn't have internal graphics you had to swap in a different graphics card. Anyone know if that's still the case?
No. You'll need to use the UniBeast installation procedure.Cant directly update from the app store ?, using mountain lion 10.8.5
