Hello, my situation is almost the same with yours Pablo, so I decided not to open a new thread and hope this is appropriate. I too search for a workstation for max 3000 euro which btw is just 3300$ right now. I stumbled over xidax website and made a configuration https://www.xidax.com/workstations/w-4-workstation-desktop/?saveconfig=38296 (a bit over my budget).
What I hope is to reduce the time of material and light testing to a minimum, I don't mind if for large stills for commercial projects I hire a farm but I feel I loose the most time with testing. Thinking that vray-rt could in part help with that I am thinking of going for 2xGTX 970 in SLI instead of a quadro 2000. (for the same price)
what do you think about this config?
