Why 6GB RAM?? That's nothing for that build. With all the other hardware you got (i7-950) and your budget, I would have gone with Crucial 8GB - 12GB. If you got the 3x 2GB sticks, you should eventually get another set of 3x 2GB to get you 12GB. (Assuming you got the Mobo that EoADark posted which has 6 slots.)
I currently have 8GB, I'm not a gamer and I still wish I had more. Don't let the RAM send you home with that "Go big or go home" rig.
