Monero sounds good. I was thinking of Dogecoin, but I always felt that its kinda looked at as being a jokecoin.
* ;)Monero doesnt seem to list the HD4870 as being able to mine.
New card to be ordered from Craigslist according to what is cheap. Or you may be able to fill the board with burner cards. You can still burn hashes with that CPU running 24/7 while you look for really cheap deal...
Doge is still a thing too.... welcome to Yobit high finance.
Yeah its a crossfire board, so i might consider trying to find two cards that will get good hash on the cheap. Problem is this board is ancient PCI-E x16 1.0 , newer cards might not POST on this thing.
