>Actually I was just looking for an illustrative example...but you are correct, PCI-E is lower voltage.
To be honest, there aren't many nameable interconnects that still use 3.3V and most of them are implemented using dedicated transceivers (from FireWire to RS-232).
USB (at 1.1 speeds) is the best example I can think of -- it requires 3.3V and is fully integrated into most I/O hubs.
However, regarding slow (100 MHz or less, give or take) chip-to-chip interfaces, 3.3V remains a fairly common choice.
And there's a lot of chips out there which are only available with 3.3V interfaces.
Ie, a couple of years ago, you'd have a hard time finding a NAND flash chip which had an interface of 2.5 or less.
