I dont understand, what does the stability has to do with performance?
I wouldnt use an unknown program to test the stability of my gfx anyway, because testing with a program that calls a few commands, on the GPU, that some video games would never use, is kinda irrelevant.
The best way to test the stability of your card, would be to:
1. Use a burn-your-card program like FurMark, in extreme burning mode, to see how your card behaves on high temps, and ofc to check how much it heats up on full load.
2. Would be to run a more "game representative" bench (like 3D mark, to see how it behaves on normal conditions.
Combine the results of the 2, and you get pretty good analysis of your gfx card's stability.
