Levi, If the motherboard slot is 4X compatible, then it should handle cards that advertise any combination that mentions 4X. So both the cards you mention should work. Going with the 4X/8X card may be beneficial because if you upgrade your mobo in the future with on that supports 8X, you can use the card and take advantage of the faster speed (although some may argue that 8X is not that much faster than 4X, and within a couple years, virtually all mobo's and graphics cards may well be PCIe (PCI express) instead of AGP.) The description you gave for the notches sounds OK, where you would have a problem is if there were tabs in your mobo slot that don't match notches in the card, this would prevent the card fromn going in. It is normal for the card to have notches in positions where no tabs exist in the mobo slot if it can accept the card.
