If you like the looks of the Formula, check the Asus Hero, very little difference other than the Armor, and built in goodies the Formula has for mobo water cooling....and just slightly more than the Pro, It's the one I decided on after about 20 assorted builds, OCs well, runs cool, good BIOS and takes everything I throw at it, which is a lot, I use it to test components for builds, upgrades and repairs, so it's seen a lot of different things and nothing phases it, run my at 4.6 with 32GB of 2666 Tridents
