I know this isn't everyone's favourite project but I just thought I'd give the Stream application a whirl.

On my HD 4870, each work unit lasts 50 seconds and gets 53.45 credit granted. That's over 92,000 credits per day, per GPU. I see that's why the stats have sky rocketed for this project.

The app itself seems a little flakey and caused the machine to be unstable unless I walked away from it whilst it was crunching. I see similar symptoms when running the RC5-72 Stream client, but not as severe.
