Hi Putz,
That's a pretty sweet sounding system. Dual Velociraptors, too. That Maximus II Forumula looks like a killer board.
I've read that Intel is most likely doing some price cuts (Q9550 for $317ish and Q9450 will be no more), product cuts, and releasing a few new CPUs around July 22. Since that is close to my birthday, I figured I'd see how prices look around then. I'm happy to see the some of the price gouging on the 4870s is going away; you can actually get one for $299.99. Hopefully, that card will be plenty for playing at 1920x1200. Although, my monitor still looks great at non-native resolutions.
I'm still thinking I'll get the Gigabyte GA-X48-DS4, but I see the Asus P5E Deluxe for a little cheaper. I've heard it is basically a simpler version of the Rampage Formula. The only reviews for it I see are the 3 user reviews on newegg, though.
