Im building a workstations strictly for Solidworks and other work related programs (Word, Excel, Draftsight etc.) We have some very complex models that we work with and currently we have a GTX 680 in our computers. It works fine except on some models it rotates very slowly and is sometimes annoying when you are trying to get something done quickly. If we decide to go to a M4000 or M2000 in the new system what kind of performance gains will we see? will models load faster? Or will this only effect rotation and things like that?
