im working on my first build and I was going to go with the x4 860k. I have a r9 270x I plan on using but I plan on upgrading to a 390x in a few months. from what ive seen online and been reading it doesn't seem like the 860k is gonna get the job done when I upgrade to the 390x. I just don't know if the a10 7870k will be any better. So im asking all of you The 860k or the a10 7870k???
