I’m new to 3D modelling, I’ve started to use Blender a few months ago. Currently I’m rendering on CPU (i5-3570, 4 core, 3.4GHz) which feels very slow so I was thinking about upgrading my PC. Would rendering on GPU be much faster than rendering on my current CPU? I have budget for something like GTX750 Ti or maybe GTX960. I’m not doing any gaming on this PC so if it only gives a small boost to the rendering speed – like 2x – It would be a waste of money for me. Should I buy a faster CPU instead?
I’ve read somewhere that if I render on GPU I can only render scenes that fit into the card’s memory. Is that correct? Will that change in the future?
Background info: I render with Cycles, I use Linux, I mostly work on large scenes but with few or no textures, and please treat me like a clueless newbie:). Thanks!
