New RTX 3060

Hey everyone - I just bought a new RTX 3060 12G (for Iray rendering) to replace my aging GTX 1080, which has 8GB of Vram.  Can I use the RTX for display and the GTX as a slave for the CUDA cores?

    I hope you mean that the other way around.

    The RTX is a new(er) card.  The GTX is a couple of generations older.

    The GTX won't be a 'slave'. You have two cards which Iray treats as two entirely separate environments. Everything  loads into both cards and they render independently. If the scene doesn't fit in VRAM of one of the cards that cards drops out of the process. You can go either way; I put my monitors on my oldest card, leaving a bit more available memory on the others. (I have a 980 TI - 6 GB, 1080 TI - 11 GB, and a 3060 - 12 GB. I used to drive my monitors with an old 740 SC but it was getting flaky, so I now run them on the 980 and don't bother using it for renders).

    Not necessarly. 
    running a titan x 12g and my 980 ti 6g together with a gpu monitor running... Both cards will be used, even if it's a 10g scene...  uses the cudas or whatever but when I was rendering the 980 would run up to it's max of vram even while the titan was at 10g used and both cards gpus were running.

    The 980 would show memory in use but wouldn't be processing if it had run out of RAM - this is the way Iray works.
