Im finding gtx 480s for $20 online. Are these cards worth it for budget mining? I know they may not be good for equihash but they are still fairly powerful so they must be good for something right? Etn maybe?
No not very useful for anything and run very hot terribly power hungry.
7970 or R290 are cheap(ish) if you have cheap electricity then those cards can be quite profitable.
Do you know of they ship abroad?
