Get a Duron, cheaper and they overclock well. Look for a Duron 600-700mhz, get an Abit KT7, and a 20-40Gb drive. Most Duron's will oveclock into the 900Mhz-1Ghz range with just a bump in voltage. The Tbirds are slightly faster, but really only noticeable in number crunching programs, so the Duron makes a better choice, even more so if you are on a budget.
I wish that all moneys from other countries were the same, as in same value. Maybe we in the US can go to the Euro! Maybe we can get the US, Canada, Austrailia, Mexico, and the European countries to accept one currency.
