Hey guys, I want to ask you an advice for a new build. I really want to make up this build and I want to know which CPU is the most powerful, just talking about a the cpu cause I'm gonna use a r9 270 as a graphic card.
Get either the 7700k or the 7850k...The 7850k is faster and 7700k has part of the iGPU disabled. It dpends on how much you want to spend. The 6800k is older and slower, on average
The 7850k is about 10% faster on average at stock, the Athlon though is a great value CPU, cheap and easily overclockable to 4.5GHz. Steamroller doesn't overclock that good, so that's a thing you want to consider especially if you're going to be using a dedicated GPU. On the other side, Steamroller is just more power efficient than Piledriver (Athlon 760K) and the 7850K's GPU is poweful enough for mild gaming and everyday tasks.
