Best cheap GPU to use?

[TheDreadPirate]

I'm trying to decide if it is worth the effort to swap out the GTX 1050 that is currently in my server with the GTX 1660ti that came out of my son's computer for his upgrade. The PITA part of that will be finding the power cable, as the 1050 gets power from the slot, but the 1660ti requires the PCIE power cable to the PSU.

There is no appreciable difference in codec support between the 2 cards.  I can't speak for the quality difference, though.  My understanding is that there was a large difference going to the 3000 series, but not from 1000 to 1600/2000.
