Up to 2 grand, Best Gaming rig available?

[Acehawk74]

Hey all.

I am looking for a new desktop PC, and can spend up to $2,000. I want to try to get the most gaming power out of this that I can, and would like some sugestions on where and what type of specs I can get. I used to be up to date on what was good and not, but I have not kept up as of late. One question though. While making ths system, would you say it would be more important to have 4gb of ram or dual 512 video cards? I'm curious which would be more helpful to me, as having both would probably price me out of my range.

Thanks for the help, and I look forward to your sugesstions!
