Did happen back on PCIe v1 days. So far I have not experienced that with PCIe v2. A good point nevertheless.

Not sure, but I don't think that's the case for the 1660, as it should have its own power connector. Don't quote me on that, though.

AM2/AM3 boards such as the one he linked have beefy power everything because, well, that's Phenom II-era AMD. It was not yet on "bring-your-own-power-plant" territory like Bulldozer, but getting there.

All true. 

Then again, if that's the case, I would throw a gazillion (read: 3) older GPUs with two video outs each and call it a day. Six monitors! POWAH!

He does have plenty of PCIe slots on that board. 

Speaking of which... is that the case, Kevin? If yes, let me know, because I may be able to help you here.

Not completely useless, but still... If it were me, I would try to find an used GPU to get by and purchase the new one when the time for a whole new machine came.

That's always a good thing to do, no matter what.
