I recently bought an rx 580 and when i tried running gta on this card, i maxed everything out but when i did and restarted the game, it ran HORRIBLY. I have an amd-fx 4300 quad core and i assume its giving me one of the worst bottlenecks i've ever experienced. I was not sure if it was either the card or the cpu, just to be sure can i get a solid answer? Newbie to this sort of stuff so i apologize in advance for the ridiculous question. I have made sure i have cleaned my drive of any old drivers before putting in new drivers
