Need new computer! Suggestions?

[Cantino]

Ok, so with the new hype of the release date (if you've read my post there you know where this is going) and all that other stuff, I need to start seriously considering where I'm going with a new computer to actually play the game without killing all the effects. When I'm done putting everything on low I'll be running the game in 2d... *sigh*

So here's my current computer:

2.4Ghz Intel processor on a generic motherboard
GeForce 4 Ti 4600
Onboard soundcard
512MB PC 2700 DDR RAM
One partridge in a pear tree

That's what I'm mostly worried about right now. I need a new monitor too but I've got some great ideas from the discussion on Kudane/Dolby's offices. =P My questions are these:

What type of motherboard should I get? What video card should I get?

I'm pretty confident in my knowledge of RAM after doing enough research on that, and I'm going to shoot for a 3.8Ghz processor at least. As for RAM I'm not sure what grade yet but I want 2 Gigs of something. Thoughts? Suggestions? Rants? Poems?
