I have a DS3 myself, haven't overclocked it yet. It's not the best motherboard in terms of regular usage, but it has a lot of overclocking features. I bought it mainly because all the overclockers were getting it, and i plan on overclocking. I don't know a lot about the Asus p5b. So it depends on what your going to be using it for. What else are you looking for in a motherboard? What RAM do you play on using, are you going to SLli/xfire?
