Summary: The P stands for no video processing on the CPU. So if you are planning to use a separate video card anyway, this processor is an excellent choice for a build on a budget - assuming the price is still ~sub $180. I saved over $40 using this CPU rather than buying a K model. You will never notice the difference between the two CPUs in actual use or game play. And with the money I saved, I jumped up to a better video card.
