so no need at all just want to spend money. that fine each to there own and all that...
Buy faster not bigger, 4 sticks is a total dog poo to use and play with. buy 16gb or 32gb but get 3600mhz+ because then at least you made things better and didnt just bin money
As for the motherboard don't, just don't it's now a dead socket there will be no new CPU's so what you have is as a good as it gets.
i very nearly spent 200 on a new board to go with my 5600, im very happy i didn't as it would have made no difference in any way.
if you game what GPU do you have, what monitor and what KB/mouse.
if we are looking to burn money buy things that make it bettergpu
