I'm in the same boat, running a 7700k and nvidia 980ti atm, upgrading to a 3900x and 5700xt gpu, new mobo and ram and everything, just gotta finish modding my case first.

I've already had a taste of the 5700xt on pcie gen 3 and its a nice upgrade. More so when it's on pcie gen 4 and with the ryzen cpu.

I'm super hyped for getting my computer finished.
