i am using a x1300 PICe card in a PCIe x4 slot so should be comparable to AGP.
The card is the 256MB pro version.
So far Im happy with the areo look and feel and speed. I had problems
getting the card initially going with vista Beta2, with only grey triangles
appearing durring the "preparing desktop " phase. the solution is found in
the threads in this forum, Search for Triangles, X1300, geometric.
