That build is... monstrous.
I was looking at the x58 motherboards a little bit; I'm getting an i7 build as well, soon. I think the EVGA will be a nice mobo, but you may want to take a look at the Gigabyte UD5 x58
It seems to have all the pros of the EVGA (XFire and SLI), except it also has a nicer PCI Express 2.0 config., which is where your lovely Core 216's will go. The UD-5 has a 16x/16x/8x setup, while the EVGA only has a 16x/8x. So, the UD-5 would give you more room for more cards, but more importantly, better bandwidth so as to take full advantage of them (and not bottleneck them).
The Gig also has 12GB more maximum memory.
Choice is yours though, EVGA is a great company to buy from from what I hear, and its board might also have more USB ports and such.
EDIT: Ok, all of that might have been useless... I think I misread the stuff on newegg, EVGA can also go 16x/16x/8x, just that you can choose to let one slot have 8x bandwidth rather than 16x. Not sure why you'd want to do that, maybe power consumption? Sorry if I confused/angered anybody with that crap.
