If I could get an opinion or two, please?

Hi, I'm a looking into buying and putting together a decent/good gaming rig. I'm fairly new to building my own machine, so I could use some imput if anyone would be so kind. I'd like for the system to play the more current set of PC games (Elder Scrolls IV: Obilvion for example) decently. I'd like to also keep it below 2,000$ if at all possible.

I did a bit of brief poking around and this is something I came up with on the fly from looking at New Egg to get some ideas. Tell me what you folks think!

I have a mouse/keyboard as well as monitor. So how do you fellows feel about it?

1) Is it viable, I mean are these parts compatible?
2) Is it a wise value?
3) Any suggestions as to how I should change it?

Thanks.

EDIT: Not sure what happened with the multiple post thing, but either a mod corrected it or it just seemed to happen by itself. Weird.

EDIT x2: Well, ahem, my bad. That wasn't the correct motherboard in fact that one wasn't even on my list. I must have copy/pasted the wrong one. Thanks for the suggestions, so what about that list now?

There are a variety of SLI boards out there, and I think you have inadvertantly chosen a socket 775 board for an Intel processor, not exactly compatible for your socket 939 processor...

Choose a single slot board, it will be quite a while before a single 7900GTX will not run a game at a desired resolution....

If determined to have an SLI board/solution, then buy two 7900GT cards ($600) outright with the SLI card....

Anybody who pisses away 140 bucks on a case should be shot. You can get a good steel case with plenty of ventilation for 40 bucks. Put a little effort into it. It's not whats on the outside. Spend that extra 100 dollars on the inside.

Buy a dvd reader/writer.

Maybe upgrade to xp-pro 64bit..,.thats where the future is right now.
