I think I would even make a further suggestion and that is if your main criteria for the purchase of your AMD AM3+ motherboard is cheap price...then you are not going to be prepared from the outset, for the rigors of overclocking an FX- 6 or 8 core processor as many of us that help around do overclock.
For those with cheap as their main purchasing criteria, it is probably best to forget the hefty overclocks you hear about all over the net and leave the overclocking to the FX processor itself which has Turbo Core built within for doing its' own overclocking where it deems it is advised and within the realms of safety.
KNOW this for a certainty, that when you overclock like most of us overclock you have IMMEDIATELY thrown AMD's specs for TDP on the trash pile. AMD has specified parameters within the FX processor that should almost exclusively save the cheaper motherboard from the scrap pile over time and should also give a pleasuable user experience which should include a mild upclock of the processor speed within AMD specs and implementation of the motherboard manufacturer.
Let it also be KNOWN that the 'instant' you induce your own manually set multiplier into the bios and thus by the designs of overclocking, you disable C1/E, TurboCore, C6 and Disable Cool N Quiet you have forced every core on your FX processor to GO to work. Not just half will be upclocked slightly as TurboCore does but 'everyone/ALL' of the cores will become overclocked and the specified TDP set out by AMD is both null and void. At this point in time it becomes almost a mute point as to whether you Disable APM or Enable HPC, the die is cast for the need for cooling and substantial VRM circuitry.
If you did not see all this coming and suddenly believe you have gotten into a forum section where the Mobo Police live and are always stressing to buy good, hefty and workable components and may seem always dissing your thought economical system purchases, you should or could have seen it coming. Without fail we have preached very much the same message now nearly 4 years. The message has not changed and in truth cannot if a user wants a good stable overclock much beyond the 4.2GHz speed with stability and expected long and healthy life span of his system components while using a 6 or 8 core FX processor. There is just too much heat and power draw to contend with to blithely say, I want to overclock my FX processor.
