PCI Express slots are found on the motherboard and are used strictly for videocards. PCI slots are slots found on almost all motherboards which powerup different cards like sound cards, TV tuner cards, USB/Firewire cards,etc. Make sure your motherboard has a PCI-E slot if you intend on installing a new video card. Old video cards use AGP and even older ones use PCI.
