iStat for gpu use?

[Cave Man]

I know iStat doesn't give you gpu core use like it does cpu core/thread use, but is there an app available that does? Bars or something that show the cores' usage?

And not being sarcastic, just never tried it.

Edit: Apple seems to have it for download too if that gives you slightly more confidence.

Not sure if their downloads are monitored like their App store. IE: with sudden and uncanny paranoia.

Super edit: I just downloaded it and I think I like it a lot. 🙂
