Ok, so recently I updated from an AMD Athlon 64 x2 6400 (3.2ghz dual core) that I got like two years ago, to an AMD Phenom II x4 965 (3.4 quad core) and now the two games that i play on PC, ArmA2 and Blackops, are running very choppy even on the lowest settings. Blackops is smooth if I stand still for a few seconds, but as soon as I move it gets worse. But ArmA2 doesn't have a good framerate at all. What would be the cause of this?
When I installed windows on the new HDD, I could not install until I reseated (and swapped slots) my RAM.
My Motherboard is socket AM2+ and my processor is AM3, but I read that they are compatible.
All my parts are a month or two old except for the ram and motherboard.
