If I got Pro Tools HD 3 PCIe & a Magma PE6R4 Expansion would Pro Tools HD run as a true 64bit application? Thus using more then 4GB of RAM?
Currently, from what I understand, 32bit apps are limited to 4GB of RAM usage per app. because of the OS.
I'd be running Pro Tools HD 7.4.1 on a Mac Pro 3.0GHz x2 8-core with Leopard OS X 10.5.1

from the compatibility docs, it looks like PCIe HD cards have to be installed inside the Mac Pro. Magma PE6R4 is for running the older PCI cards with a newer Mac.

Pro Tools HD 7.4.1 requires ONE of the following Pro Tools|HD configurations:
Pro Tools|HD 1, HD 2, or HD 3 PCIe system — 1 Accel Core card and up to 2 HD Accel cards (PCIe)
HD PCIe Cards must be installed inside the Mac Pro
See Pro Tools HD 7.4.1 Read Me for information on installation instructions of third HD Accel PCIe card in slot 4
Up to 6 Pro Tools|HD PCI Cards — installed inside the Magma PE6R4 6-slot expansion chassis
Pro Tools|HD PCI and Pro Tools|HD PCIe cards cannot be combined in any system
For more information, see the Magma PE6R4 Expansion Chassis compatibility page
