So I have a 6600k from a computer I acquired without an "overclockable" motherboard. I was hoping the community could help me decide if I should invest in like, an AIO cooler and a Z270 motherboard. With that, I'd overclock it and hope for GPU prices to go down, and upgrade it from the gtx 970 card it has. Does this sound like a good idea? Or should I just wait for prices to drop, save my money, and start fresh? Thanks for any advice you give. I'll list the specs of the PC below.Keep in mind this is my brother's old 2016 PC and he got the CPU for cheap, and didn't care about OC, which was kinda dumb in hindsight.
Mobo: ASUS B150 Pro Gaming/Aura
CPU: Intel i5 6600k
GPU: ASUS STRIX GTX970 DC2OC 4GB
RAM: Kingston HyperX FURY Black 2133MHz DDR4 16GB (8 x 2)
PSU: EVGA 600B 600w
