You don't need that board. At the most get a V Pro. Infact,a Gigabyte z77 ud5h is full featured. Anything more expensive is unnecessary just for gaming. Otherwise seems legit.
I completely agree there. I also think the HAF X is quite a bit overkill. You could use the HAF XM and shave a good $50 - $60 off the price tag. Or you could use something like the NZXT Phantom or Corsair 400R and save even more money - and then SLI that 660TI. I don't get the idea behind the caching drive either.
