Hi, I have a home-built box with a Gigabyte GA-MA69G-S3H M/B and an AMD X2 4000+ (ADO4000IAA5DD) and I am looking to upgrade the processor. The PC spends most if its time idling so I thought I'd try to reduce the power consumption while increasing the maximum speed for when I want it. I do not do any gaming and only the occasional home video editing and photo editing (among other things). I am considering the Athlon II X2 240e or something in that range. I don't see the need to go for a more expensive 3 or 4 core processor.
I have seen some processor comparison charts on click here and I am comfortable about what I see apart from on thing. On the Gigabyte site for this M/B there is a comment "(Note) If you install an AMD AM3/AM2+ CPU on AM2 motherboard, the system bus speed will downgrade from HT3.0(5200 MT/s) to HT1.0 (2000 MT/s); however, the frequency of AM2+ CPU will not be impacted." As the 240e is an AM3 CPU what will be the effect on its speed?
