Looking to build, any suggestions?

I have been looking to build a system for a little while now and just recently acquired the means to buy one. I feel that this system should be great, but I'm looking for suggestions before I buy in terms of things that may be incompatible.

So far I have:

Antec 1200 Case
2 LG sata cd/dvd drives
Seagate 640 GB 7200 RPM HDD
Sapphire Radeon 4870 X2
Corsair CMPSU 1kW/modular
8 GB G-Skill DDR2 800 PC2 6400
Asus Rampage Formula
Q9550 quad core
Zalman 110mm CPU cooler

I think this should all work together but I want to make sure. Also, I was hoping to wait for the core i7 and x58 chipset to come out, however I need to order before the end of the month and I doubt the new intel stock will be out by then. Anywho, if any of you see anything wrong or anything that I could switch out that would make more sense or be better in your opinions, feel free to post.

Thanks again,

Ausmus

Your original list of parts will work together. I'd go with the above suggestions.

There's a major problem with Nehalem right now - DDR3 can't be higher than 1.65v or kiss the cpu goodbye. Performance ram will always use more than stock voltage. If Deneb, out in 01/09, lives up to the hype of 4.3Ghz on air, I'm gonna be deflecting back to AMD. All it needs is DDR2 & SB750 mobo (cheap). I'm eagerly waiting for real-world overclocks at XS.
