Building a new computer

[One Winged Angel]

I have most of my parts I'll be needing. Here's the spec list.

Video Card: Nvidia Geforce FX 5600 256 mb

Processor: AMD Athlon XP 3000+ "Barton" processor CPU.

Motherboard: Aopen AK790 400 max Motherboard for AMD.

Case: Shuttle Case, looking more into it.

RAM: Crucial Miero 512 MB 64 x 64 PC2100 DDR RAM.



There are still a few things I need to get, like a CD drive and audio card. this is my first comp i'm building on my own, so will my video card support HL2 and Doom 3? I just need something that will last awhile.

I'm deciding whether to get Audigy Platinum or Audigy 2 card. does anyone know the sound quality between the 2 is?

one more thing, I'm in really need for a few USB 2 ports. Do all mobo's have USB 2 ports now or are they much more expensive?
