Can you use 2 non SLI GPUs in Blender with 2 different architectures an example a geforce gtx 560 and a quadro fx 4000.

  • $\begingroup$ SLI makes two GPUS act like one, which will actually make cycles go slower than when using the two GPUs in parallel (without SLI) $\endgroup$ – gandalf3 Feb 26 '15 at 21:18
  • $\begingroup$ Do note that GTX and Quadro gpus use different drivers, and while using both in the same system work for some, it's not necessarily plug and play and/or problem-free. (According to some internet posters, I have no personal experience.) $\endgroup$ – nik10110 Feb 27 '15 at 22:48
  • $\begingroup$ The gtx and quadro cards are examples the actual cards I am wondering about are a geforce gt730 and a geforce 560ti $\endgroup$ – SupaKoopaTroopa64 Feb 27 '15 at 23:06

In one system I use different architectures:

  • GTX 660 Ti - Kepler
  • GTX 980 - Maxwell

this does not prove that it will work with all combinations, but as long the drivers support CUDA (true for both GPUs you listed) it should work fine.
