Hey, everybody -- I'm in a situation where I want to upgrade my laptop. I have an old Dell Inspiron 1100, with the unique presence of an upgradeable socket 478 socket with 400MHz FSB inside... It's got a Celeron 2.0GHz chip in there now, and I'm looking to upgrade! My question is... What makes more sense? Get a new Celeron 2.8GHz chip like this one for about $35, or try and get a true Pentium IV at around 2.6GHz for about $80 (which seems to be what they're going for)? In your expert opinion, which one will be better bang for my buck?
