Vidya card test

sup /comp/

Is there a program out there that runs a test to see if my video card is working ok? I've already done various tests on my memory and updated to all my latest drivers but somehow I still get freezes and weird things happen.

Also on an unrelated note, what are some must have optimizing programs or clean up tools to have? I'm currently on vista 64.

Thanks.
