has new feature which allows you to o'c on the fly by using a dif computer(any laptop)
only has crossfire support, but i don't see this as a con because your in the 5000 series...
"Maximum OC with confidence with burn proof protection to chipsets and GPU!
The COP EX allows overclockers to increase chipset voltages without the worries of overheating. It can also be used to monitor and save an overheating GPU. The COP EX allows more freedom and less constraint for maximum performance achievement."
great to have when you O.C
edit: you where talking about future proofing right? is this going to be the only build you do for the next 3-2 years? or is it a 1 year thing? because if it's a one year thing i would go with dangtx but if your going to be keeping it longer then i would suggest the mobo and same as dangtx cheaper ram... also to give you a harder time on picking a case take a look at the sniper black edition very nice case here are the 2 reviews that HWC did...:

No need to tri-fire with a ATI 5970. It'll be able to play all the games out there except for maybe Metro 2033 if you crank everything up. With this said, get the Corsair HX850. It'll be more than enough and you get modular goodness, making cable arrangements a breeze.
Both Core i7 and the Phenom II X6 are great CPUs in the $300 range. You'll be satisfied with either one. Do know that with the Core i7, you get 4 cores with 8 threads. This makes it possible for you to run -bigadv folding for our folding team
I agree laptops are not the way to go for gaming, unless of course $$ is not a factor at all, and dont expect a light gaming laptop. The whole thing would have to be built from top to bottom to be a gaming laptop, something like the Alienware ones, and those are $$$.
