It varies. Unless if you're an enthusiast gamer, you won't notice a much of a difference between that CPU and an i5 in gaming. If you're doing 1080P you will be just fine.
I currently use a FX 8350 for my PC and it does just fine for gaming. I used an older athlon II x4 previously and it was enough for what I needed to do 2 years ago. A newer model would be fine for current gen gaming.
