I am a gamer and i want to upgrade my CPU. Right now my processor is an AMD FX 8320. It has served me well but i think it's now the bottleneck of my rig. Before i go picking out the best CPU i can get, i want to know if it can be supported by my motherboard, the gigabyte 970A-DS3. my budget is about £200 however i could go over by about £100 (maybe). what is the best CPU i can buy.
