Video Cards for dual monitor set

I have a 7970 radeon that runs rather hot even with alot of air flow, quad boxing atm and with dual monitors wanted to know if I can just grab another card to split the work load so I can have my Main monitor with my higher powered gpu and a second with the 3 followers on the second without crossfire for my other monitor , Really want to know if it will work out , and try to lower the temps

And if anyone knows a good system for aftermarket cooling of 7900 radeon gpu would cool beans

Yes, I've personally 'split the load' for both WoW and FFXIV across my GTX 580s.

cant even try it now if I wanted to this new aftermarket cooler xtreme 7970 covers up 5 slots lol but it keeps the 1 gpu cooler 30c at full load >.<
