I guess I never much understood this dual gpu / single PCB design, here's why...
Either
A) It performs close to a 2900XT (probably still less than a 2900) yet will cost MORE than a 2900XT. Why would you spend more money on something that doesn't perform as well as it's bigger brother?
or
B) It does outperform a 2900XT (probably by a realllllly small margin), in which case why didn't they make a dual 2900XT card for SERIOUS horsepower? Probably still costs more than a 2900XT.
Now, if it just underperforms a 2900 series card and actually costs less as well I can see it. But I just have a hard time seeing a dual GPU card like this actually costing less than 2900XT which will more than likely outperform it. I suppose it's premature to make any of these remarks but this is what usually happens on these damned dual gpu cards.
