Desktop recommendations ?

[motivation]

I am planning to buy a desktop . So I went to dell web site and started to customize it . But I don't know really what would be a good choice for the future in most of the options . SO I surf the web more from HP and others

The CPU will be mainly duo 2 quad .

1) OS , vista or XP ?
2) Ram , 2, 3,4 ?
3) LCD monitor type ? I can get 2 19 inch with the price of 1 monitor 24 ? I am between ( samsung , HP , dell )
5) video card , how that would affect my usage ?
6) mouse and keyboard ( logitech 99% )
7) any thing imporatant ?

So what do think experts ?

It all depends on what you want to do on your PC.
1: I use Vista but XP os is faster for games (dont get Vista Basic)
2: 2gig is good in Vista 1 Gig for XP if not using to much for games.
3: LCD is a personal thing I use a 19inch ask your friends what brand they use, I have a View Sonic which I brought after reading about it in a mag.
4: very important, games or not?
5: yes I love them I use a G5 mouse for gaming Dont like wireless as I go through to many batteries (except for lappys)
6: hard drive get more than you need.

get the best you can afford. the best dual core or even quad core 2 gig ram or more, a super fast graphics card with 512 ram. that way come 2 or 3 years time. your have a decent spec still. i can see by 2012 cpus will be quad core, maybe dual quad cores and running a 6 ghz per core.
