8320 does better than i5 on passmark scores, and its cheaper. Also if you multi task (play game while listening to music and have a web browser open) 8320 will do better. I just built an amd system for my father in law and he plays hitman absolution and sniper elite 3 on ultra with no problems. Just get a good cooler like a hyper 212 evo and a 990fx motherboard.
