I just really want to thank you for all the help you've given me, I know some basic things and how to build one but i'm not a computer expert so the help has been really useful! ?

Ok, i've gone through all of the list, I choose 6 that really caught my eye, I compared all of those to eachother and found that the MSI B450-A PRO was the one with the cheapest price and with the right features. So this board would pair good with my Graphics card and CPU? Or is there some kind of problem that my CPU can't overclock on this board or something? And I cannot thank you enough for making that list and helping me finding all this stuff, i'm kinda new to PC building so thanks for all the info.

Best would be a board of about 100 dollars but if you find a better board for a little more I would be willing to pay more for a better one

With the 2600 about 100 - 150 euro's or about 110 -170 dollar I'm a european from the Netherlands so prices may be a little different from the US

I've found a motherboard that should be compatible B350 Tomahawk https://www.msi.com/Motherboard/B350-TOMAHAWK/Specification

Hmmm ok so my best option would be buying a new motherboard with right socket, and buy a Ryzen 5 2600? My budget rises a little higher than that, would a 2600x give better results or about the same, not only targeting gaming?

I'll just list some of my specs to make it a bit easier - ga-b150-hd3p Motherboard - Gigabyte RX 580 8gb gaming Graphics Card - Intel core i5 6400 CPU - 8gb of Ballistix ddr4 sport LT 2400 CL16 (2x 4gb dual channeled) - 500 WAT power supply I could look for another motherboard with an amd4 socket for maybe an r7 2700x or something like that

So I recently upgraded my grahpics card from a Gigabyte r9 270 2gb to a Gigabyte RX 580 8gb gaming. My current CPU is an intel core I5 6400, I have been experiencing pretty severe bottlenecks where my CPU is at 99% and my GPU at 40% with 25 - 50 fps and stuttering in Call Of Duty Black ops III at medium settings. So to fix this I want to buy a new CPU because the one I have now can't keep up. What CPU should I buy? My budget is around 300 euro's (340 dollars) I've had my eye on an I7 6700k, would this be a good option? Does anyone have any suggestions? Any other fixes that might ease the bottleneck? -GingerLion
