I’m working with an RTX 2060
That's a 6 yo GPU with 6 gigs of VRAM, and the (comfortable) minimum for realistic/non low poly scenes in Cycles would be ~8 gigs rn. So yeah, either switch to EEVEE or download moar ram buy yourself a new n shiny GPU, i am afraid >_<
The other things i can think of: get the latest GPU drivers, and also the absolute latest (or at least the latest LTS) version of Blender, that should help. And don't forget to turn the GPU rendering on in the global settings too (for Nvidia that should be at least CUDA, or even better - OptiX).
On the remaining HW: for the CPU, something with 4+ cores and somewhat recentish (like 5yo tops maybe) helps a lot too, just like 16+ gigs of RAM - which won't only help but could be a requirement for some larger/fairly complex scenes, else it's a good recipe for OOM crashes.
P.S. here's a lil guide on some useful Blender rendering settings, hope it helps ya to bring the rendering times down and the quality up~
P.P.S. and if you want something even more in depth (if slightly outdated), here's a good one too.
Cheers!
