Yeah swap the triple RAM for some dual channel. Sandybridge don't support it.
Whats the main use of the computer going to be? if games than the 2500K will be a better option.
Noctua NH-D14 and Thermalright Silver Arrow are the 'best' air coolers at the moment. However if money is tight, the Akasa Venom and Gelid Tranqullio are decent coolers for their prices.
Nice choice of mobo though![]()
