I want to sell my I5-7500 and ASROCK B150M-HDS MB and buy a new CPU+MB, what you guys can tell me, which is the best for 144Hz 1080p gaming?
I wouldn't expect a huge jump over the 7500. For just gaming you're still best off with a i7-9700K or i9-9900K (or KF, KS variants). Add a good CPU cooler and overclock 'em.
Ryzen 3600, 3700X come pretty darn close. Gaming and streaming, the 2700X has something to say, although it will fall a little behind on the pure fps side of things.
