hey every1, Im in the market for a PM, and i came across a used dual 2.5. What are the differences between the older 2.5 and the new dual 2.3 and 2.7s? How do they differ in hardware specs and speed? Any info you can provide me with would be quite helpful! Thanks, -Zach EDIT: been comparing the specs and it seems everything is the same with the exception of a 900mhz FSB instead of a 1.13/1.25ghz FSB. How much will that affect performance? And will the extra CPU speed offset that?
