Thanks for your answers, I've decided to buy a pentuim g4560, 8gb ddr4, and a new asrock b250m pro4 matx mobo. I feel like this is the better choice, otherwise I probably would've had to upgrade to another lga775 cpu, which is too expensive for not great performance increase, and I can still only use my 2x4gb ddr3 at 1333 mhz
