You are getting like 4 of those 2gb kits right?

Ram is so fucking cheap, I don't know why everyone isn't just maxing their boards. So what if your OS can't see it now, in a couple upgrades it will and you'll be balling.

I spent less than $150 and have 8GB ram. And it was only that expensive because I got low latency stuff. Hell you can get 4gb ram for that beast and only be a little bit more than what you are spending now, still keep you under $600.
