Some:
Dual Xeon 2.4, HT enabled, 4 instances: 84x84x84x84 = 336
P4C 2.8s, HT enabled, 2 instances, no overclock: 105x105 = 210
AMD2600 = 168
P4E 2.8, HT enabled, 2 instances, no overclock: 93x93 = 186 (pitiful, just pitiful)
P4E screams on NEP, runs right with the Xeon, but sux on most everything else. Anyone want to trade me a P4C 3.0 or 3.2 for it? Terms available.
