Before I start Pls explain what you mean to say.. I can accept your opinion towards Stress test.. But that.... And for your knowledge I already used it when I had prob with my GPU. It is better for testing your GPU.
I give you my example I had very rare problem, Bsod occurred only 1out of 20 times.. So their is two ways to test it either play for long hours or do a test.. And for testing purpose it is a good tool.. their is also many settings in it so you can control everything.. You don't need to go for burn in test .. do a test in little low res.. and their is also temp(decided by you) warning so when it rings kill the test and move out.. simple only people who fry it who has incompetent Psu or go for very high setting on their incapable GPU. and most importantly who is not careful.
So better use your words wisely.
