What is the advantage (if any) of an AMD Athlon II dual-core over the earlier Athlon 64x2 which was also a dual-core AMD? BTW - a technician in a branch of a well-known electronics chain mentioned that both would work with either a socket-AM2 or socket-AM3 m'board, but that a socket-AM2 will only accept DDR2 RAM whereas a socket-AM3 will only accept DDR3 RAM... Don't know if this is true.

Athon IIs are available now. The earlier X2's are not. The earlier models were AM2 only, the newer ones are AM3.

There is at least one motherboard on the market that can take any current AM2/AM2+/AM3 processor and run it with DDR2 memory. An AM3 processor will almost certainly need DDR3 memory only to work.

OK, thanks for answering... I really just wanted to know the advantages (speed, etc) of an Athlon II over a 64 x2, and at risk of a contradict - there are a few 'e-tailers' selling the 64 x2, but again, thanks
