Buying used/refurbished GPUs: Is my questionnaire complete?

[fgervais]

Greets,

Both for mining and other uses I occasionally purchase used GPUs, especially if the card will be in a high-stress, low survival environment.

When ascertaining if the cards I'm looking at are worth the price/at all, I whip out this little questionnaire:
1- How old is the card?
2- Was it pulled from a system running 24/7?
3- What type of use was made of the card?
3.1- Any super stressful use like mining?
4- If known, what was the average temperature?
5- Was it left stock or modified?

Since a lot of you guys must have been doing this for longer than me, along with a test on one of my own systems, am I leaving something out?

Yes, you forgot #6:

6.) Have you ever lied to help make a sale happen?
