You can very well avoid this if you optimize character textures )
On fingers:
a standard set of character textures takes ~2-4 gigabytes (4k) and the computer shows the middle finger with 5 characters, but for such a render in FullHD it is enough to reduce the textures to 0.5k and 5 characters can easily fit where there used to be one.

~500 MB optimized textures (0.5-1k), ~1000 iterations in FullHD (99% quality) and... ~1 minute render time on GTX 2060Super (also true for 4k render).
By the way, with a limited budget I recommend this video card instead of buying 1080, 2060S faster.
