I really don’t think it matters much, for my workflow, to really get serious until I can get a couple 24GB cards for a good price. All the optimizing for GPU is giving me flashbacks to optimizing for CPU. My longest Render times for interior or exterior are around 2 hours, so I’m good with CPU renderings. I had do dig for power, for my 1080, but it was laying under other things. I thought I was screwed and I was going to remove the 980ti, but after digging, I found power. I think that I’m maxed out on everything, so I better be content for a couple years. I have invested $10 grand this year, so far. I was mainly referring to Max in general I remember you were having some Viewport issues. It’s been a while since I submitted an Autodesk ticket but I remember they were quick to ask “are you using certified hardware” and stuff, maybe that’s not the case anymore. ---

I’ve been buying up used titan x maxwells for the same price as 1080’s. More ram and just as fast for the same dosh. If you have a machine or GPU with less ram than the one with most ram, I would sell it or not use it for rendering only for view port. ---

What are you comparing the Titan X Maxwell too? The 1080? its not in the same class. The 1080 is a beast for gaming kills the Titan X Maxwell in that aspect but for raw cuda performance it’s on par with the a Titan X Maxwell. ---
