I upgraded my computer a bit, but it took (as usual) longer than I expected when the above design obsolescence stuff was tossed at me. How about "Out of Memory" Error Messages with Large Amounts of RAM Installed - support.microsoft.com/?kbid=253912

PCI slots are such an integral part of a computer's architecture that most people take them for granted. - not any more
Smaller PCIe cards will fit into larger PCIe slots. The computer simply ignores the extra connections. For example, a x4 card can plug into a x16 slot. A x16 card, however, would be too big for a x4 slot. http://computer.howstuffworks.com/pci-express.htm
I can now reboot between two operating systems with the flip of a switch, have two monitors running, and plug in five hard drives (but can use only three at once).
