Definitely go for the Maximus V Formula - It's the BEST motherboard out there for a gamer.
I have a Maximus V Extreme which is more or less the same. The audio on the formula is absolutely mind-blowing!
Overclock Ability - AMAZING.
Stays Cool - Hell yeah!
SLI/Crossfire - No problem at all!
RAM - Easy to overclock a ram, just the clicks of a few buttons.
The best part of these ROG motherboards is the UEFI bios it provides.
Here's a story - Before I bought my Maximus V Extreme - I never overclocked anything other than my graphics card cuz my stupid old computer didn't let me overclock it even a bit! After I bought it - I tweaked every single part of my PC including the video card, the CPU, the RAM - Everything and now sir, I'm the MemTweakIt PRO Overclock Rank.4 worldwide. Just because of these absolutely mind-blowing motherboards.
If you have any problem regarding the board - Hit me up whenever you like!
