I have old r9 280x cards doing nothing in the storage room. Finding this thread, I don't want them laid to waste. If I use them to mine ETH, can they still get around those hashrates nowadays?
No they can not. If I remember correctly they only have 3gig of ram and eth now needs at least 4gig.
You can however mine things like ubiq, Ella etc tha have low dag but you have to have free or extremely cheap electricity.
Best bet, sell them for 40-50 bucks, but your coin of choice and wait for it to go up.
