I assume its an AMD 1.5 Ghz Processor. If so go to www.newegg.com. Do a search for Abit NF7-S. Its a kickass mobo that has built in ethernet - built in 5.1 dolby surround sound card on the motherboard and the chipset of the mobo is made by NVidia(the graphics card company). Its a great motherboard. Abit has really good driver support too.
