AMD because dollar to dollar, their low end stuff beats out Intel's, and that's a lot of what I'm buying not only for my needs (Athlon 64 x2 4200+ isn't high end, but thats what I run and I can game fine) and money is always important.
I think AMD will survive. It's not like they are crap cpu's they just can't match Intel right now. They're great if you have a really tight budget. They get the job done. Having an Intel won't save you from getting stomped on UT3
