Yeah. P3's rarely went over the 1Ghz mark - it must be a P4. On that spec (1.8Ghz) I run MAME 0.105 (still a pre-core change build) sweet with just a bit of lag on the KI+chd games, 3d fighters were still emulated poorly but PS1 emulators will run mint at that spec to fill all your fighting needs. N64 runs brilliant at that spec, as does Laserdisc, Mega CD, Jaguar and others.
