I was under the impression 4GB would be enough! I'm on 64bit Vista, but still, 4GB ... don't want to spend more money there. I've ordered the 9600GT!

[Disclaimer: I haven't played PC games since like 2006, so any game suggestions 2006+ are OK!]

I've got $300 bucks to spend! on games! PC only of course. Any ideas?

I've got COD4, World in Conflict and Crysis already.

So now I'm looking for Rise of Nations kind of games, building something, doing war, etc. any new games like that?

Also I'm becoming a big fan of COD4 (just from the videos on here), so I do like these games in which

we're a miliaty power or something.

Thanks for your suggestions!
