So I have built 5 rigs of 4-6 GPU's that have all run great for the past 14 months, 2 of them were bought off Ebay. Not the Rigs themselves but the Cards. At the time it was hard to get any and resale was the best option. Now I have been seeing a lot of resale on Ebay so I built another rig last month, and still no issues with except it went down 4 times in that period, and I was able to start it right back up. My question is has anyone bought resale and had issues, before I buy more resale cards I wanted to see if maybe I have just gotten lucky with my purchases and others have had issues. Thanks!
