I'm trying to learn about all the options in cgminer for a 5970, and I'm a tad bit lost.

I'm playing with my rig so I keep restarting cgminer. I've got another card in the rig; these are just my 5970 GPUs. It is in a full tower in an air conditioned server room, so your rig might run hotter with these same settings.
