If you are spending under $200 on a chip AMD is the way to go. The one chip having a higher frequency than another doesn’t exactly may if faster; their design is different which make them perform different. Look up the bench marks of the chips you are looking at and then look at the programs that you use to see what performs best. The people who bring up ‘far superior’ and i5 have not read all of the forms here for good information. The i5 and PII 965 trade blows with i5 wining a few more by slight margins and overall costing about $50 more.
