i56500

I currently have a i5-6500 and I am bottlenecking a gtx 1070. I was told a Ryzen 5 2600 would be an upgrade from what I can tell it is. Is it worth the upgrade though? Or if I am upgrading should I just go for the 3600 for the extra $100? Or is the 2600 even that much better than the 6500?

Ok so i have a fx 6300 overclocked to 4 ghz, a asrock 970-a mother board, hyper 212 evo cpu cooler, gtx 1060 3 gig, 1 gig of ddr3 ram clocked @1866Mhz in games my framerate is not great i mostly hover at around 55 on high or ultra settings but i get awaful studdering i am wondering if i should...
