So I've had this hp for a few months (was given to me from a friend), and I've upgraded its gpu but the cpu bottlenecks so badly that I can only run gpu bound games and still get frame drops. I'm looking to upgrade from the horrid am3 socket to a lga 1150, but I have no idea what mobo would fit in this case, and I'm wondering if I should just buy a new case/mobo combo. Also the specs are: gtx 960 4gb, 6gb of ram, amd athlon II x4 640, 600w psu. Thank you in advance
