There is no effective performance difference between using the PCI-X and PCI-E versions of these cards; the cards are essentially identical, with the addition of a PCI-Express bridge on the PCI-E card. Keep in mind that even if you use 4 E1 circuits with the card, the total bandwidth consumption of card is approximately 1 megabyte per second (4 times 2 megabits per second), which is drastically below the PCI bus bandwidth of 132 megabytes per second (33 MHz bus with 32-bit transfers). No quad-T1/E1 card will ever be able to saturate a PCI bus, especially not PCI-X or PCI-E. -- Kevin P.
