It seems like most people on here are running multi-GPU (3 or more vid cards) rigs... am I the anomaly in that I'm running a single card at the moment??

I'm running XMR STAK with a 980 GTX and i7 4790K getting 815-825 H/S combined (CPU and GPU)... is that decent? I'm thinking of adding an RX 580 into the mix, but I doubt my Corsair Gold 750W could handle it?

Yes, you have to put more gpu's to your sistem, in order to increase ROI
and it all depends on the price of one PCI-e slot = if your PC's price is 1000$ and have 4x PCI-e and you are using all of them - then it means one slot's price is 250$.
But if you use only one slot, then the price is 1000 which is expensive
