i believe it is a chipset limitiation with the memory. just talked with dell sales support. though i wont say it as a final answer, but they said they arent planning on selling the 7900 series like they sold the 7800 GTX, at least not at this time. may be a few weeks before they may change their mind (inventory availble) or we may have to find a backdoor to purchasing it.
