I suggest you go to a local store, ask for a 1GHz Athlon, as long as they have a recent stock, they should have an AXIA, ask to look at the core before handing over the cash or check or whatever you pay with. If it's not an AXIA, walk out. That's what I did, and now I'm at 1.6GHz.. Consider the extra you pay when buying local your "pre-tested" fee.
