In the crazy and non-conclusive research I have done I'm looking for opinions. Is there a benefit to buying say 2-3 GTX 480 vs 1x GTX 670/80? There are also some relatively cheap Quadro 4000s around at the moment too, as another option.
If I did just buy a single GPU I will likely keep my 285 installed for the secondary card with DaVinci Resolve.
I do mainly modelling and FX work in Maya with VRay, Mudbox, CS6 and Nuke.
Any thoughts appreciated.
