if i wanted to build a mining rig, would it be better for me to buy a USED GPU? With the rapid devaluation of computer parts, i can potentially get more computing power for my dollar. has anyone considered this? would this work? are there any problems with this?
It all depends on the price! There are some gamers that keep great care of their parts, keeping all boxes and packing and either smart or no overclocking. I know there is no guarantee... but when I see someone has kept everything together and clean it gives me a good feeling about the item. So far it has proven to be correct.
