What is good?Which one is better?

I've been told that intel processors are the best and fast growing product that most people and techs are choosing in the computer industry. We use Windows XP - not a lot of people here use Mac computers.

I will give you the information of what you need. Since technology is advancing every minute, every week, every month and every year - you have to know or want to know what is recommended, what's popular, but what is quality performance - If you're talking about the best processor worldwide - The Intel Core 2 Duo and the Core 2 Quad - no processor can keep up with its powerful speed and performance. Mac systems are even using the new Intel C2 chips - now if I were to choose Mac OS X or XP - I'm a PC User so I'd use XP - even over Windows Vista. Now if I was a Mac user yes I'd choose OS X over XP - for one the setup of Mac OS X, configuration, setting up network configuration on LAN or wireless is pretty simple -just like Windows XP - for troubleshooting times - I deal with more bugs with XP than I do with the MAC OS X - that doesn't mean XP is not a stable Operating System - it is! But with the fact that hardware compatibility problems happen more often with Windows XP due to Blue Screen Errors, memory errors - Now of course Mac Systems are built by companies and not by us. - Bigger difference why most MAC systems don't deal with much problems with hardware compatibility issues.
