MemTest86 a lot at work on customer's machines, and it's great for troubleshooting memory issues. My question is, how can I test that a GPU is starting to go?
I know of programs like 3DMark to push the graphics card to its limits, but what about with Video Memory? Is it worth testing? Is there a stress tool actually able to catch issues in the video card (memory), perhaps using CUDA/OpenCL?
