But...
I got it from Techspot.com...
"Like the Phenom range, the Athlon II X4 620 is capable of operating on either AM2/AM2+ or AM3 motherboards, and thus inherits the ability to use DDR2 or DDR3 memory. This could arguably be a way to provide users with a viable upgrade path a few years down the track, but for most the case will be about picking up the cheapest and best performing parts today."
Is it true..?
