I think I can be flexible so as long as I pick something up that's really going to last me. I really don't want to go over $200 I'd like to know if it's worth upgrading my CPU on a $200 max budget. I'm running GTA V on medium to high settings with at 35-45 FPS on overclock.

For the last few games I've played (AC Unity/GTA V) I've been able to shoot up my graphics and maintaining the SAME frames per second as I had on my lower settings. I was told that my CPU was bottle necking. I guess my CPU can't keep up with my GPU's capabilities? Here's what I have: http://www.newegg.com/Product/Product.aspx?Item=N82E16819103727 Here's what I think I want http://www.newegg.com/Product/Product.aspx?Item=N82E16819113326&cm_re=quad_core-_-19-113-326-_-Product Here's what Rockstar recommends: http://www.newegg.com/Product/Product.aspx?Item=N82E16819113284 So here's my confusion. I'm seeing AMD CPUs where it'll say (3.4ghz) with a price higher than the 4.2ghz I'm looking at. Rockstar's suggestion is 4.0-4.2ghz 8 cores, but the one I linked is $60 cheaper. I think I'd rather go with 4 cores for now, is this really going to make much difference from 3.4 to 4.2?
