Built this machine to handle gaming at 3x 1080p screens. With a solid upgrade path to Ultrawide 1440p when it becomes cheaper (Which is actually easier to run). Only reason I went with the Crosshair was because Deepcool refused to offer a mounting bracket for the DeepCool Captain 240 (non EX). And it was cheaper to grab the Crosshair, than to get a whole new Cooler. It can handle triple monitor gaming when overclocked at around 40-60fps in the most demanding titles, such as Witcher 3, set at Ultra. Enough that I don't notice a difference.
As for the shockingly low prices. That is a combination of savvy shopping, Ebay, and Microcenter deals.
