As far as I'm aware, unless the card is specifically the Mac Edition series, it *should* work OK in a normal PC.
Are there any markings at all on the cards to denote they are specifically for the Mac?

I'm presuming they're PCI-e, so you may want to try them one at a time & see if you can get a result that way..

Macs don't have a BIOS (they use EFI), so the VGA BIOS is probably much different from the PC version of the card.

Yeah I'm not totally clear on all this but since the advent of Intel Macs there aren't specifically Mac and PC versions anymore but there are definitely differences still which may or may not be related to EFI vs BIOS. My Mac Pro at work has an 8800GT. It looks just like any other Nvidia reference model and it works just fine in my PC at home (in fact use for PhysX sometimes). However, any old "PC" PCI-e card will not work in the Mac. I tried with a 3650 I bought from Newegg coincidentally enough and got no video. So if these 3650s are really from Mac Pros my (admittedly limited) experience tells me they should work fine in your PC.
