You seem to have a high spec suggestion there, so I assume money itself isn't a big problem.
But for the CPU, I think you should stick with the 920, the added price for the 950 isn't worth it. You can easily overclock a 920 to about 3.6, probably even more around 3.8ghz. The CPU cooler you have is massive, and looks like it'll block some RAM slots. I use this-http://www.newegg.com/Product/Product.aspx...N82E16835608014
I got my 920 to 4ghz with it, but I just keep it at 3.9ghz now. You'll also need to go with a 64bit OS to get the best out of the i7 and tri channel RAM, use 3x2GB sticks of DDR3, you could get 12gb or 6gb.
If you're going to spend that much on that Intel mobo, I'd choose this instead it costs more but it's awesome!http://www.newegg.com/Product/Product.aspx...N82E16813188048
Really though DJPace is right too, you could get a cheaper mobo that'll do the same job. I myself use a P6T Deluxe V2. Fitting the RAM will be a tight squeeze with a Noctua Nh-up12(if you use all the slots that is). And with that V10 thing or whatever it is, I'm not sure you could fit all the RAM in, that thing looks massive and totally unnecessary, especially for you as a business man who might need all that RAM. You'd benefit more from using the Noctua cooler, or even the Mugen 2 would be good(but it's more a budget cooler).
Also, I do recommend you get the new ATI 5xxx series cards like DJPace said. They're awesome!
And for your harddrives? You could consider getting Solid State Drives, I'm currently waiting for my Intel X25 80GB to arrive(not the black color one, it's a generation 1 drive that won't support TRIM, the Generation 2 which is the white ones, will support this, I see them in capacity of 80gb and 160gb. If you want excellent performance you could RAID 2x160GB Intel SSD's, the will be pricey but well worth it! And you would need to get Windows 7 when it comes out to support TRIM(basically the SSD equivalent of a Defrag).
I can't seem to find the 160 versions of the SSD on US sites, but this is the white one I'll be getting.http://www.tigerdirect.com/applications/Se...&CatId=4147
Also, what about a Power Supply... You're gonna need some immense power for that machine, people will probably suggest the Corsair HX1000 Wat. But this is the best PSU in the world right now-http://www.newegg.com/Product/Product.aspx...N82E16817194040
I regard Enermax as the best PSU company followed by Corsair. A review can be read here.http://www.pcper.com/article.php?aid=671&a...xpert&pid=8
