You can use newer AM3 processor with AM2+ socket board.
But cant use the AM2+ processors with AM3 socket board.
You cant even find PhenomII X4 940 in the market these days.
@OP. Yes u can use the PhenomII X4 with DDRII, AM2+ boards. But then whats the point of changing platforms when you are going for one generation old AM2+ board instead of AM3, DDRIII, SB850, USB3.0 ones. Its not a worthwhile change of platform. Thats why i asked you to change the proccy to a Q8300/ used Q9xxx and OC them slightly. Going for PhenomII X4, AM2+, DDRII is not a worthwhile upgrade IMHO.
