>what do you think I should go for?
Depends on your budget, but some kind of 2060 Super or 2070 Super would be good. I'd start with a GPU upgrade since it'd be easy to use in a new build if you decided to do that later. You can just throw the old GPU back in if you decide to sell the full rig.
>I'm new to the hardware world and worried that I'd fuck up majorly
It's not as hard as you probably think. Just make sure to do some research first. /pcbg/ on /g/ is a good place to start if you've got more questions.
