So there's tons of overclocking guides to single core AMD processors, and it's relatively simple. But I may be getting a dual core amd, and i really have no clue what the differences are other than the multiplier can go up? What are the advantages of having a higher multiplier and lower fsb? and vise versa? I see that a lot of air cooled 3800's that are at around 2700 are above standard voltage, sometimes up to 1.6+ (on air!). Do X2's run much cooler? Any more info would be greatly appreciated, thanks
