I would like to buy a 6990 with at least 3 displayport connections. I think they all have it though. Might also be willing to trade a 7970 towards it.
Just curious, why trade a better card (7970) for an inferior one?
The 6990 is a better card depending on application. The 7970 is more power efficient, the 6990 can do more hashes. Gaming should be better on the 6990 of noise is not an issue.
