Hello, I am newbie, My name is Zeke

I am building a new computer(basicly my first) and I am going with an Athlon 1.8Ghz or a 1.9Ghz, Is that Ok? Should I go ahead for an XP 2000?
First of all, are there any major problems with Athlons that are surpassed by the pentium?
But more importantly, What would be the right, or a good motherboard for an Athlon of said speeds?
I am going to be using this new computer for gaming and web-design. Also, are 4 memory slots really uncommon? or Is it perfectly possible to get a motherboard with 4 slots? And how many PCI Slots do I reall need? I will definitely need an AGP slot as well. *Summary* What is a good motherboard for an Athlon with an AGP slot and enough PCI and Ram Slots?
Note: I dont really want to trouble myself with overclocking, if at all possible.
