All northwoods have an "a" or "b" after them, and come in even denominations: 1.8a, 2.0a.2.4b, etc. The a's are 400 fsb, and the b's are 533 fsb. Your cpu is a willamette core with 256 megs of cache. I recommend one of two boards that are reasonably priced: the gigabyte 8sg667 with sis 648 chipset and agp 8x support, or the albatron px 845 pev pro with the Intel 845pe chipset, support for hyperthreading, and pc2700 memory. The albatron board has an agp/pci "lock" feature to keep your cards in spec when overclocking. Both boards are available at newegg for $85-93.
