Hello, i know this has been asked many times on threads, but i havent found a satisfactory or complete answer, also alot of threads are for older gpus/cpus, and also budget is not a big concern for me as i have 20k$ to spend on a workstation pc if need be. I am looking to build a work station pc for autodesk software: autocad, inventor, 3dsmax, alias, and maya. rendering, animation and stress testing. i am trying to find a combination for a dual xeon cpu build, or a single i7, gtx 980 or a quadro series card. I think i have decided to go with a xeon processor for high number of cores for rendering. but im having trouble deciding bewtween a gtx or quadro. I heard even within workstation requirements (using autodesk programs) gtx cards work better for rendering, while quadros work better with animations. I know quadros are built for long rendering and animation times and stability with ecc.; I am fairly new to animation but in the future i am going to be doing some fairly complex animations for products im currently designing. I was wondering if someone couold give me a good break down for the pros and cons of each card type. not just the basics, but what features and tasks each card is better for. and while i have a large budget i could easily spend 16k on 4 quadro k6000, or 4k on 4 new gtx 980 kingpins. as much detailed information as possible would be good.
