I'm thinking of upgrading my athlon 1.2 to an XP sometime in the future, probably 1700. The thing is, I'm going to have to replace my mobo too if i upgrade since my epox 8k7a doesn't seem to support the XP chipset. Is it worth it so spend around $200 just so i can have a +.2 ghz increase in speed? Or should i better spend it on a graphics card?
