If you are going to oc, you should get a Asus or Gigabyte motherboard. Skip Intel.
The motherboard has the options that allow overclocking in the bios.
Yes indeed. Intel Core i7 mobo's only have the backbone of a Core i7 system with some small features here and there. Other good mobo brands such as ASUS, Gigabyte and EVGA have that same backbone with lots of extra features and mostly better components surrounding the chipset for better OC's if you choose for the more top-ranking boards.
These things can make your life a lot easier if you plan to use the board in a more 'advanced' way like overclocking or bios-flashing.
BTW if I'm not mistaken, Intel core i7 boards don't offer triple channel memory, only dual.
So make out for yourself. Do you plan to OC the cpu or play around with memory timings/freqs., then go for the 'non-intel' brands. If you plan to simply install the cpu and ram and never tough it again, leaving it all at stock, then it might be an interesting option to buy an intel board for a very decent price.
