That's ridiculous, and in all honesty, I'd be willing to be that isn't your real reason, just your pretext. On my 2700x/X470 system, when I first built it, I got into all that tweaking, I was able to push my 2700x to 4.4Ghz all core at only 1.3125v, did the RAM timings calculator, etc etc etc and you know what, I didn't notice a single difference in my daily use, in the way my games played or how quickly my videos rendered, so I said screw it, just left the PBO on, and again, didn't notice any degradation in performance.
While tweaking can be fun, I truly believe that it's a placebo effect that can only be seen in a benchmark,, in other words, I'm sure all that tweaking only gains 1%-2% performance which isn't even perceived by a human being... What I'm saying is, staying away from a better platform because you're worried about having to put in some time to accomplish a 1% performance increase that isn't even noticeable is ridiculous.
