Now I'm wondering if I should swap to an Intel i5-9600k instead of the Ryzen 2700? It'd be this:

The intel is better unless you're going to be heavily multitasking, I'd go with the intel unless you really can't afford it.

what Sin said, nice Rig though.

I'm also a big advocate of getting a 144hz+ monitor if youre getting a brand new rig.

not very often i agree with gayboy, but hes right about 144hz :)

im not gay i get with tons of hot chicks all the time

I ended up getting a Ryzen 2700x. Can take it back for up to 2 years, we'll see how this goes haha. I figured 8 cores + hyperthreading would be useful for building Chromium, and for most of the games I play it overclocks to within 15% of the i7-9700.

Here's the benchmark scores:

Overall I'm happy with it so far! Windows is actually.. kinda refreshing? I'm going to dualboot Pop!OS too.
