Upgrade build or buy new prebuilt?
I have a pretty old build that's been slowing down on me, considering just buying a prebuilt since most prebuilts have way better specs than my current build (as well as the fact that I don't really play any heavy games, the "heaviest" games I play are probably Overwatch and Fortnite), but I'm wondering if it may just be worth it to upgrade certain parts on my current build to catch up.
Specs: RTX2060, Ryzen 5 3600, 4x8GB Corsair Vengeance RAM, ROG-B 450 Gaming Motherboard. Case is an NZXT and I have a Kraken liquid AIO.
