Erm? no, My AM3 DDR3 CPU drops right into an AM2+ DDR2 socket and works perfectly right off the bat with DDR2 memory.
We have had this discussion before, AMD only change there sockets when they absolutely have to, and even then they design the next generation CPU to fit on the old one so you don't have to change the socket if you don't want to or are a bit short on cash.
Do Sandy Bridge CPU's have DDR2 controllers in them?
There is no reason why AMD would not continue this with the GPU controller change.
What the hell are you talking about?
To get PCI-E 3.0 you would need at least a new chipset & Board (Given you know that AMD's PCI-E controller is in the chipset, not the CPU), it'd likely come from a new socket (Moot point even if it didn't, still a new board)
So much ignorance when it comes to AMD and sockets in general.
More of Humbug talking about stuff he DOESN'T know about?
I would say that the cost of DDR3 is so little nowadays that there's no point in sticking with AM2 on that purpose alone.
It was also completely irrelevant to PCI-E 3.0.
He was trying to slam Intel while praising AMD.
Although, his praise for AMD on the IMC front is valid, although completely irrelevant.
Although, can be a double edged sword, 3 sockets with no real CPU change (Phenom II ran on AM2+/AM3/AM3+, but some people will have gone through that platform upgrade continuously for no reason and no performance boost, some AM2 boards could take Phenom II's too, so could be said 4 sockets of Phenom II)
Isn't that just testament to how good the Phenom II series was, I applaud AMD for that, but again, as I said, that's a lot of sockets without any real performance improvement.
EDIT : So, just so I'm aware, I'm an AMD hater/Intel fanatic, who knows more about the AMD platforms than the AMD users who defend them? Then exactly how am I meant to win
