I used to use the MSI Kombustor , but the msi site doesn't show the lastest version. Heaven benchmark doesn't seem bad. But are there other alternatives that will stress the gpu?
This is probably silly but I just run 3dMark 2003 in a benchmark loop when I'm troubleshooting a graphics card. May not stress it. You can do distributed computing, like SETI, that will max your GPU out!
