[ArmaHolic ArmA 2 Optimization]

What would be a recommendation for the PBO files to use for someone with 3 gigs of ram on RAMdisk? And how should I set it up if required to do so differently?

I've been looking all over the place for a website (doesn't matter which language) or some place that currently sells Arma 2. But that is pretty hard for me -being an America-, So I need your guys help just posting a few links to where to purchase the game online..

Preferably download only, Since I'm fairly impatient with waiting for things to arrive in the mail. This could also be used for others usage too.
