Pentium 4 Motherboards
From Vogons Wiki
Socket 423
Socket 423 was the first Pentium 4 socket. It was rather short-lived, but still went through a few changes in it's life. Most Socket 423 motherboards used RDRAM instead of the more common DDR or SDRAM.
Today: Theres not really a reason to build such a rig these days. The 2.0GHz Pentium 4 is about as fast as a Tualatin 1.4GHz while consuming a lot more power.
Socket 478
Today: There are four major cores available for this socket: Willamette, Northwood, Prescott and Gallatin. The most interesting are perhaps Northwood and Gallatin. Gallatin is the Extreme Edition chip, a rebranded Xeon core with L3 cache.
Socket 775
Otherwise known as LGA 775
