My results may arrive later than you expect. I originally had two W5700X MPX modules, and I recently replaced one of them with a 6900XT. when I use both GPUs for export in DaVinci, both GPUs are around 30% occupied. When I formulated to use the 6900XT single GPU, it reached about 50%. The single 6900XT exported a little faster than the dual GPU. My guess is that the W5700X module is limiting the 6900XT. The results might be better with dual 6900XT.Anyone using Davinci Resolve? I am trying to figure out if it will be happier using a mix of MPX + stock reference card ... or simply having two stock reference cards instead...

Remove it unless you really need thunderbolt video output. The 580X actually slowed down my performance when i had both 6900XT and 580X in the system.Is the consensus still to remove the MPX card if you are installing an RX 6900 XT?
