I'm just fed up with AMD switching to the new socket type. I bought an X2 939 chip about 18 months ago. I'd like to be able to upgrade it, but for some reason they launched AM2.
As far as I can tell, there seems to be no reason AMD to do this beyond DDR2 support. They're not (noticably) faster. AM2 doesn't give you anything S939 did.
It just means people who already have S939 kit will have to buy all new mobos, and RAM, and to be honest who in their right minds is going to do that when they can get C2D for about the same price?
