This is the game. It's called:
"How fast can you build a full desktop?"

Here are the rules:

Can't bust 800$ limit.

Has to be complete: Sound, hard drive, cables (Only optional piece is the case, I can pull rabbits out of a hat)

What I've been beating around -

Connect3d X800GTO modded to X850XT speed
2gig of value ram Corsair brand minimum
3200 64 939 chip
80 gig hard drive ( I don't download a lot )

What Im confused about -

Motherboard, primarily. I see all these numbers and symbols and I get confused.
Sound card, I want to hear the games/movies good but I dont' really know what point in sound becomes "overkill" considering budget.
Ram speeds, I don't know what ram to match with the CPU and the front side bus, all I know is, I DO plan on overclocking at some point, but only to give it a slight edge that puts it in another level of detail at "playable" frame rates. I don't care about SLI, since my budget doesn't condone it.

A few disclaimers-
I might be able to push the budget to 1000, but that'd take a lot of heart and I wouldn't feel right doing it since my mom's pitching in. I feel like building my own rig gives me the capability of building a rig with nice specs that doesn't cost a fortune. (800 dollar home built will beat any 800 dollar box desktop into the ground when it comes to benchmarks)

I already have a retail unregistered version of Windows XP professional so I don' have to worry about the operating system.

deff agree with the sound.

I've have basically the best first nFORCE based board released with killer sound. the a7n8x Deluxe and all i can say is this thing sounds excellent.

matter fact i just Cranked up my Klipsch 2.1 and my PLantronics DSP-500's and played the COD2 demo and man you feel like your at war!

I actually researched a lot of yours and Ruggers' posts and bought a few pieces on my own, now I'm built up.

This is what I"m using:

Chaintech VNF4 Ultra Zenith E motherboard
On-board audio, (I haven't tried it on surround sound yet but I'm sure I won't be disappointed)
Sapphire X800GTO2 Pci-express (Flashed to 16 pipelines, yet to OC)

I'm really happy about flashing the videocard myself successfully. I have never flashed before and I'm confident I can OC under stock cooling if I take precautions.

I ordered Geil dual channel value ram, but it has heatsinks/dividers. I won't be OC'ing the ram.

The CPU I have is a 3000+ AMD venice 939 socket

Can't wait to play games with my new rig
