the tbirds and durons seem to be similarly priced.
the tbirds are faster due to the extra cache for those tasks that need it. MHz = that is...
if all you do is surf the net, get the duron and save $10 bucks.... =) of course i am not talking about getting the fastest athlon compared with the fastest duron...
the durons are an excellent value, as are the slower athlons...
i'm looking at tbirds myself...
