The Bottom Line
The ASUS P5K3 proves to be another motherboard founded on stellar engineering culminating in great stability, excellent performance, and solid overclocking prowess. This is an expensive motherboard however and once you factor in the cost of DDR3 modules you are going to find yourself easily above a $600 upgrade investment.
Had we seen it outpace other motherboards in top end CPU bus overclocking it certainly would have been worthy of a Gold [H] Award. Still the levels of overclocking shown on the P5K3 are nothing short of awesome and will likely fill the needs of any overclocker other than the super-hardcore.
