A PM is a better processor for gaming. Think of it as giving similar performance and having similar weaknesses and strengths like the AMD Athlon 64 family. The Pentium 4 is better for power apps and really has no competitors in that arena. I'm giving my DAD my P4 cause he is going to use it to run SQL/Oracle and other database apps. I'm getting a Pentium M myself and am going to oc it and use it for gaming and animation and photoediting and web design.
