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.
(I am now firmly in the "RGB is dumb" camp like the other grumpy old people. Oh well.)
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!
