Quote from: BenJ on June 09, 2020, 01:03:11 AMHi all,My current PC setup is as follows:Ryzen Threadripper 2990WXGigabyte GeForce RTX 207032gb RAMI mainly render detailed car interiors so scenes can be pretty heavy (around 150-200m triangles). While the Threadripper can chew through anything that I throw at it, I would like to explore the benefits of using GPU rendering. Unfortunately when switching over to the 2070, on most scenes I'm getting an out of memory error.I'm considering upgrading to either a single or dual 2080 Ti setup. Can anyone shed any light on the performance gains I could expect from this GPU setup? Unfortunately I was unable to access the benchmark tool.

GPU will sometimes be very close (but usually can be done much faster) and sometimes is way off--colors are off, reflections and shadows change, new artifacts are introduced.I usually use GPU (2080ti) for my preview as I'm working as it is much faster (even with my 3970x processor). But it has screwed me several times as I have wasted hours trying to tweak something that was only there because of the GPU rendering. Several times changing over to CPU fixed everything. Very frustrating.
