I read that the (newer) 7xx series of nVidia cards are not fully supported yet. Apparently CUDA support is not only limited in blender; reviews of such cards seem to indicate that they don’t work with other softwares either. An example is the detailed comment here:
My question is, is it just a matter of time before the new 7xx series is supported across Blender and the other platforms, or is it a better idea to buy a 6xx card? I like to sink my hard-earned cash into graphics cards about once every 5 years.
Thanks for the consideration.
