I’ve got a PC specialist rtx 2070 and it handles most editing jobs just fine. Nvidia do “Studio” drivers that you can install . The biggest issue I have with it is really the noise. It’s almost as noisy as my PS4 pro. 🙂
If it’s purely for editing then (I can’t believe I’m saying this) look at the new Apple M1 chip products. These are the first ever chips built from the ground up by Apple and the performance in heavy duty editing software is just insane.
I’m actually considering getting a mini M1 myself purely for editing.
