P5K, the board that i have : two 16x PCI-e , one 1x PCI-e and 3 pci
P5K-E: Adds more Raid options with Intel matrix storage, Adds Wifi, optical out, and more copper but no heat-pipe (useless anyway)
P5K-Deluxe: same as the p5k-e, adds the RJ-45 and even more copper.
Very similar boards, i would get the deluxe for the **** of it.
