All INTEL stuff.  Told a lot more stable.
LOL! I love that statement..... My question for most 
computer geeks would be, 'What processor are you running in your own 
computer?'. 
I would be the last one to say which processor is more stable. It's been my experience that the O/S and the programs a user employs have much more to do with stability. There are a ton of benchmarking programs on the internet so it's fairly easy to check your computers' speed and stability. 
While I would never list myself as an expert, I've built lots of computers myself with both AMD and INTEL processors. (NewEgg is like a Candy Store to me) Both work well and provide great stability in my opinion. Choosing one over the other is more a matter of personal preference unless the user is prepared to do lots of benchmarking. 
Computer geeks are susceptible to mass marketing just like the rest of us. 
What I can't figure out is this.... Why would a 
computer geek put a 80gb harddrive in a new 
computer these days? The difference between a good 320gb and a 80gb harddrive is less than $40 these days.
Fish......
