PCI-E is the new format and practically all new mobos support it.

select your "CPU Socket Type" (754 or 939), select how many "PCI Express x16 slots" (1 or 2) you want and you'll have a bunch of mobos to choose from.
I'm looking to upgrade my exisiting Graphics card, and have seen the Nvidia 7600 GT. However, this card is PCI-E, and my current MoBo does not support this.
Are there any Mobo's on the market that support PCI-E AND and AMD Athlon XP 3000+???
I'm guessing the answer is no, but I'd like confirmation before i buy an AGP card.
