As i understand it the AGP X800 XT's built by ATi are all PE's. Other vendors don't call theirs' PE's but they are the same thing. Once the PEG XT comes out there will be confusion, as there will be an XT PE and an XT PEG version of this card (at different clockspeeds), but the AGP version will only be available as a PE. It would seem that the board parters should start adding the PE to the name of their AGP XT's as well to help reduce the confusion.
