I can only guess this is for gaming. It's still barely there for UHD 4K gaming so this is a little overkill on RAM but good GPU for the nice 144Hz 2K gaming monitors.
There are so many compatible motherboards that I don't advise such today. I stick with best sellers and give the nod to gamers like we see at https://www.reddit.com/r/PCMasterRace/wiki/builds
I wanted to know would these parts be good in a setup or would anyone have any better advice, I already have the ram and processor but I can't think of a card and motherboard that would go well with it so I need advice since I'm not so good at this stuff.
i7-7700k 4.2ghz cpu, the socket of the cpu is 1151 lga
32gb of ram DDR4, it is dual channel so two 16gb sticks of ram
