I have a few 7300GT video cards that were pulled from first gen Mac Pro's when they were upgraded. They have been sitting around for some time, and i'm looking to sell them on eBay. Since these were not my personal machines i'm not aware if there was any issues with these cards. They all boot up fine, but i'd like to give them a decent test to see filter out any bad cards before selling them off. Unfortunately there is no video test with the ASD suite for first gen Mac Pros. I was looking at trying to run some bench tests with a third party program, but the ones i've looked at (GPUtest & Luxmark) won't work (the 7300 doesn't support OpenCL for Luxmark, not sure why GPUTest doesn't work...) Any ideas on a test that i can put the cards through? thanks in advance.
