I’m building a new PC and discovered it is possible to have 2 different models of GPU of the same brand (nvidia in my case) in non-sli mode. My plan now is to use my ancient 2gb 660 ti as a display card when rendering using the new 3080 (it’s a big upgrade) thus freeing up the 1-1.5 gb vram windows seems to always use for display purposes and so I can do some modelling / watch a video on the 660ti without any issues.
My question is whether this actually works: I’d have both cards plugged into the same monitor in different inputs, for general usage I’d use the 3080 (displayport) as the display card and when it comes time to render I’d change the input on the monitor to the 660ti (hdmi).
Would the 3080 automatically be removed as a ‘display’ card and the vram freed up? If not could I do this manually in software? Will this be more trouble than it’s worth?
