Fellow geeks, Help me build my new computer

[ScottTheFish]

Ok, it's new computer time. I build all my own but it's been over 2 years and I haven't kept up with the hardware stuff like I used to.

Here's what I know so far:
- $1200-1300 budget
- AMD proc(64 bit? is it worth it yet? Any software taking advantage of it?)
- 1 GB RAM
- already have a 2001FP, so no monitor.
- I want best bang for my buck, not the absolute fastest available. Buying the fastest cpu/vid card available is for suckers. double the price for 10% more performance, no thanks.
-no interest in overclocking, etc.

I need advice on mobo/chipset, I want onboard sound, LAN, USB 2.0, etc.

cpu speed, whats the best speed right now for price/performance balance?

Best bang for the buck video card...always been a Nvidia guy, but I could go either way, no holy wars, please [img]/images/graemlins/laugh.gif[/img] I do some gaming (HL2,Doom3, etc) so I need something pretty beefy. Dual DVI would be good, but not mandatory.

Appreciate any advice.
