I was wondering if i should get a 6300 with a 7770 ghz or an Athlon 750k with a 7770 and 6570 i have the right mobo and i mainly want to play next gen and current gen games at good setting and fps! i don't really want to video edit that much maybe some light video editing and hardly any live streaming! I don't even know if those two cards are compatible to crossfire. Thanks!
