What is the compatibility of an R9 290x in the same system with an R9 380/380x or other cards? Any crossfire support?
No.
R9 290x was rebadged to R9 390x with more ram and higher clocks.

I have a 700W power supply, I need an 850W to be 100% sure I don't burn down my house.
But could I, for at least a week, underclock the piss out of my processor to keep in compliance with my PSU's power rating?
I'm not looking to game, only mining Ethereum
