Well from what I've been seeing lately, the 7700k is still king of the hill regarding gaming and I don't play MP games, so it seems it will be a great upgrade from my 2500k.
From what I have seen I am looking at about 50% more gaming performance in cpu limited cases and around 100% in apps. If the 2500k lasted me so long, I believe I will be ok.
I think I am going to challenge you on that^. These reviewers can't even remotely back up that claim, that the 7700 is the best gaming CPU. I run three different i7 gaming rigs & understand, that for any and every benchmark you will see with a 7700k in it, is with ONLY that benchmark running...!
Unfortunately, that^ is not how Gamers, game..!
So these benchmarks are completely invalid, because they exist in a sterile vacuum. Intel is business, and it's technology is having a hard time reaching the Gamer. I see my 4790k struggling with Battlefield, so much so, that I can't multi-task.
Also, I still am confused as to what Coffee Lake is going to bring? Or what chipset, etc.
I've never been one to be fuddled by Intel's road map & direction, but what a mess all this skylake-x thing is. Intel seems all rash, moving their portfolio around reacting to Ryzen. It is hard to tell rumor from fact. Released dates are getting moved, etc.
Also, sitting here I am having a hard time wrapping my head around Intel's new platform. For me, the 7700 does little over an OC 4790 in games. I am looking for bigger gains if building a new gaming rig. And when I do upgrade/replace that rig, it will be with 8core, or higher.
Is that coffee Lake..?
