New build for the new year

[Stryder75]

I am planning a new build for the new year. I would like to ask for your opinions / suggestions on my component selections.

CPU - e6600 http://www.newegg.com/product/product.asp?item=N82E16819115003
CPU cooling - Coolit Eliminator http://www.coolitsystems.com/
RAM - G Skill http://www.newegg.com/product/product.asp?item=N82E16820231065
This is where it gets interesting
Motherboard(s) P5B deluxe http://www.newegg.com/product/product.asp?item=N82E16813131045
or COMMANDO http://www.newegg.com/product/product.asp?item=N82E16813131149
or P5W DH http://www.newegg.com/Product/Product.asp?Item=N82E16813131025
or should I look into the 680i chipset.

The only reason I am leaning towards the p965 and 975 is for ATI crossfire support. I currently have a X1900XT and plan to purchase the R600 (X2800 series) once available. I want to keep the X1900 for the rendering + physics solution ATI has planned. I have not seen any word that this will not work on the Intel chipsets. I have looked at the DFI RD600 board, but the performance does not seem to be on par with those of Intel and Nvidia.

Would like to know what you guys think, since alot of you have experience with the motherboards I have listed.
