It looks like AMD shipped an AMD 64 chip with 512 instead of 1 Gig cache for almost 1/2 the price. I read a review that showed that it was almost identical to the full $400 AMD 64 chip. The only area which showed much difference was in games.

An excuse to pick up the latest 64bit mobo and take this puppy for a ride. It is priced about the same as an Athlon 3000 XP, but the potential (with 64 bit) is greater as apps and Windows 64 take advantage of it.

I can't find the review again (it was only released last week), but the home page of www.newegg.com (on the left) shows it. Also at http://www.newegg.com/app/viewProductDesc.asp?DEPA=0&sumit=Go&description=19%2D103%2D424&searchdepa=0
