Why would you want that? Your current worker is already using your GPU's full power. Splitting that wouldn't help... What you might want is a backup pool for your computer to use in case slush's goes down or something.
ATI 3200 doesn't support mining. Only 4xxx series and above.
Ah, thank you for answering both my questions. I appreciate your time.
-How would I go about setting up a back up pool in case my predominate one goes down? As well, in the same breath, which would you recommend as a good back up choice?
