I saw that miner for Turtlecoin reference somewhere else.
You do realize that your 1.5-2 khash on Monero represents the output of a SINGLE Vega GPU?
On the other hand, I've got more than a few "older" machines or parts from older machines working on various projects, far be it from me to condemn anyone for "recycling existing hardware".
BTW - what is a "RX 590?" Never heard of such a thing before now.
Yeah I figured why not get some use out of my older hardware and mine some coins slowly rather than spend a huge amount of money on GPU's and possibly never even break even. And my bad about the 590, it was a typo from an article I was basing some of the info off of. The Xbox One X should be the same as a 580.
