I have an AMD FX-8150 at 4.2GHz and it's been performing slower than what it use to be, i had it for a bit over a year now. I currently have a GTX 560ti and I want to replace it with the 770 and I don't know if my CPU can handle it. If it can't, what should i get? The FX 8350, FX 9370, or is it REALLY worth getting an intel ( I will get the 4770k if it's a big difference, and I have to buy a new motherboard). I mainly use the computer for gaming (World of Warcraft, League of Legends, and sometimes high-end grpahics demanding RPG games)
