Unfortunatley no, it's either one or the other not both. If your looking at the P5K series you may want to look at the P5K-E. You get onboard wi-fi that you dont get on the P5K-C. Also, DDR-3 only gives you marginally better performance than DDR-2 at this point. You wont see a point to use DDR-3 memory until we get processors with a native 1600mhz FSB which the P5K-C may not have support for.
