Build is in sig. I either want to upgrade my CPU or GPU. If I go with the CPU, I was thinking about the i9 9900(non K or KF). If I looked at my Qualified CPU list for the Z370 Extreme 4 correctly, I should be able to move up to that cpu with this board, right? Not too worried about overclocking, TBH. If I go GPU, I was thinking the 5700XT when the custom cards finally get released. I'll be gaming at 1440p, so which direction should I go for the best experience, for now? Whichever one I don't go with now I will probably do, towards the end of the year.
