Personally I have stuck with Intel, currently PIII700. I do so because of the following:
1. Cheap, reliable motherboards. Using Asus CUBX 440BX at the moment.
2. Performance-O-Plenty for everything I do.
3. SSE, not a huge deal by any means, but it seems like it is catching on.
I don't think Athlon/Duron's are bad. The thing that shy's me away are the motherboard chipsets currently available. AMD's 750 is somewhat of a dog and I just can't get myself worked up over VIA chipsets.
Also, I don't really understand the "Chipzilla" stigma that Intel has become pegged with. Yes they are big and recently they have made a few minor mistakes (Not like AMD has not had it's problems in the past). OK I'll grant you that the PIII 1.13Ghz was a large type blunder. Intel is, however, still a very innovative company and has done more for the PC than just about anyone. As for Intel wanting to maximize profits on their product, if you were an Intel investor or employee I don't think you would be singing the "those bastards" tune. I kinda like the competition that has developed between AMD and Intel over the past year, and I own stock in both companies.
OK, I'll get off my soap box. Good luck with your new system.
