I also have the PCI-E to PCI and a radeon 7770 that I do not use that I was planning to use in my sam440ep-flex but without 3D support I haven't bothered yet. I know the 7770 is overkill over the slow PCI bus but since I don't use it it's better then buying something else.
Waste to use PCI cards on PCI machines? Not really since it's faster then the old PCI cards we can use even over the PCI bus plus the large amounts of memory if able to use in the future, well if drivers get useful that is.
To TS good luck selling
