Exactly....Ahhh! The old Megahertz (or in this case, Gigahertz) Myth. Core and Core 2 based CPUs are much faster than the old Pentium 4 CPUs at the same frequency. A Core Solo @ 1.5GHz is about the same as a Pentium 4 at 2.25GHz. Core Duos are even faster because both processors are active. Most game manufacturers base there minimum specs on Pentium 4 numbers.
