Hyper99,
nobody is feeling bad about buying anything.
-If I'm going for a new setup, Thunderbird all the way. It's cheaper and faster than anything Intel has, or I go for a Duron because its so damn cheap, overclocks great, and cost at barely over 100.
-If I have a solid BX board and I'm on a tight budget, I get a Celeron II and overclock it to 100, or for a little more I go for the 600E.
You want to know the difference between the 4 different setups?
NOTHING!!! Because I sure as hell can't feel the difference between 50fps(ever since the 450A with a TNT2) and 999999fps. Websurfing isn't getting any faster without a T3 line, and I'm sure my figures are the limiting factor to how fast Microsoft Words types my document.
So to answer your concern, nobody is regretting anything. Each product has a solid niche in the computer junkie market.
