I bit the bullet and upgraded from 4670k + DDR3 --> X570 Mobo + R5 3700X. Costs ~$500 assuming you can keep your GPU, PSU, Case, fans etc. and you don't want to go all our RGB on everything.
So yeah, I made some questionable technical decisions purely for aesthetics but yeah form is kind of important too.
i have 0 RGB on or in my case.
your comment just made me change my view on RGBs. I.Want.Them.
My next built is going to puke rainbows! its gonna have a builtin display for a unicorn which moves according to the load - walking on <10, running on >60. its gonna be amazing!
(I am now firmly in the "RGB is dumb" camp like the other grumpy old people. Oh well.)
