How do you know which GPU is rendering

Hi guys,
I recently got me a 4x 980ti system. And I'm quite confused with the devices in the octane settings. It seems to me that it changes all the time the assignment between the Gpu0, Gpu1, Gpu2, Gpu3 (see screenshot) and the corresponding cards in the computer. What I want is to enable low priority for the viewport GPU only.
I checked it by rendering with only one card and than touch the cards to see which one is getting hot. But I don't know maybe after every restart it's getting mixed up again.
Do you guys have a tip for me how to deal with it?

Viewport card is that monitor connected as you know. You can find it by just enabling one card for render. Try some render expensive scene to render in LV. And play with camera while render is going. If you see some lags that's monitor card.

I use AfterBurner to indicate and spectate temps and usage.
BTW in what motherboard and what GPUs you fit there?
I wanted to buy 4 but Asus X99 fit only 3 with stock GPU cooling.

For my multi-980ti system, I use a splitter to have up to 4 external and 1 card internal. External is great for heat. My MSI motherboard seems to only want 2 GPUs on board, though I was hoping for 3 internal. So after much trial and error, I settled on 1 card internal and 4 external. And I'm building a duplicate system as well. But my second system is now on pause after the announcement of 1080 cards. Hopefully Octane will start cooking with 1080s soon!
