not really much you could upgrade to, 6990 is already one of the fastest gpus available. maybe get a second 6990?

7970 isn't really an upgrade from the 6990. there are definitely aspects of the 7970 that makes it more desirable than the 6990, but speed isn't one of them.

7990 is 2x 7970 on a single card. so yes, it's worth the money. and a 7990 would be faster than your 6990. it will be equally hard to cool, however.

81C is a fine temp for the 6990.
