What i do is use Manage 3D settings in the NVidia control panel. In the base profile under CUDA GPU's you can select which cards to use for GPU rendering. If a card is turned off, it will not appear in the Poser GPU selection

If a card/multiple cards is/are turned on, you still have to select them in the render settings in Poser, or you default to CPU. Depending on the scene your card selection is likely to change. From what was said at the webinar, and personal experience, if you exceed the Video Ram of the card(s) the render crashes. So you will have to pick and choose based on what is in your scene, your tile size, and your particular video cards. What may work in one scene, may not work in another.
