Hello everyone! Need some help. I'm planning to buy:
1) Core i7-8700;
2) ASRock z370 Pro4;
3) G.Skill Aegis 3000 CL16 8x2GB;
4) Crucial mx500 500GB\Samsung 850 evo 500GB (which one should I go for? is difference between them nociceable?);
5) Macho rev. B\Hyper 212 Evo\Hyper 212x (not sure because of 6 cores at 4.4);
6) XFX XTR Series 650W;
7) Overclocked GTX 1070\2060

So, what should I change? What about this PSU? Is there anything better for this price? Maybe 550w enough for this build (oc 1070\2060 with 8700 in Turboboost) or I should buy 650w PSU? Can't choose PSU and cooler for a long time.

Is fan on this XFX XTR good? I wanted to go for Seasonic, but I read about their fans and decided to choose the other one.
