express card and I wanna upgrade? Are they still making card on the PCI express 16 slot? What are my best options to upgrade my current card to a card that performs better and works on the same slot system?PCI 2.0 is not the same thing as PCI express 16.That's why Im looking for a card that can work on a pci express 16 or known as a PCI X16 slot. I need a card that would also offer a sensible performance upgrade too. Don't want to go up there and spend 300$ or more on the same performance different model number. In spring 06 the 7950 was the top card on the market.
