S939, S940, and AM2 Questions

[timswim78]

Are S940 and AM2 the same thing?

Are S939 CPU's compatible with AM2 motherboards?

 

[myocardia]

1. No, they have the same amount of pins, but they aren't compatible.
2. No, they don't even have the same amount of pins.
3. They all have different names, because they are different.

myocardia hit the nail on the head.

If you don't have any existing hardware, get S775 instead. Unless you're on a shoestring budget.
