It's a good deal. The only problem is that AZ11e does not support 133Mhz bus, so you will be stack with 100Mhz bus Athlon.
In a long term, you might be better off getting one of boards based on KT133a and an OEM chip for about the same money or $10 - $20 more from places like Newegg although I prefer getting retail chip over OEM.
