German website Computerbase.de is reporting, that there are several users out there, who have received GeForce 8800GTs, which do not have the usual 112 Shaders and 256 bit memory interface you would expect from this model. Their cards seem to have only 96 shaders and an 128 bit interface. While the 128 bit interface is clearly advertised, the 96 shaders are not. This would make the card even slower than a 9600 GSO. The problem is, that these cards are still being sold as 8800GTs and you won't know that you have gotten a slower one, until you check it after installation. The card in question is from Point Of View with the model number
R-VGA150868.
UPDATE: Looks like one affected user has heard back from Point Of View, he will get his card replaced. All shops selling this card should clearly advertise it as 128-bit variant. The number of shaders on the R-VGA150868 product is intended to be 112, not 96. That's why Point of View offered to replace the card.
Update no. 2: Both Point Of View and NVIDIA have commented on the issue. Point Of View states that they are only the first to offer this card at such specs and other manufacturers will follow. Meaning, that all 8800 GTs will suffer this change. NVIDIA on the other hand is not aware of any such change and has underlined, that Point Of View is acting alone on this one.
