Hey guys, I have a few dollars to spend and want to pick up a used GPU or two. It looks like Nvidia is the way to go, especially for Folding, but I am having a hard time letting go of my desire to participate in projects like Milkyway@Home that use DP. Too bad most Nvidia cards, outside of Titans, are just terrible at DP! I've been trying to buy used R9 280x's, but the last two in a row have been duds and had to be sent back. Not sure if I want to try for a third. Looking for some ideas for good all-around GPUs that can be put to work on whatever the TeAm needs at the moment, hopefully less than $250 each. Maybe it's foolish to keep looking for cards that can do it all, instead just dedicate certain GPUs to certain tasks, but with my limited resources, maximum flexibility is a plus.
