The motherboard is an AsRock pro3 Z75- http://www.amazon.com/gp/product/B007P709YI/ref=ox_sc_act_title_1?ie=UTF8&psc=1&smid=ATVPDKIKX0DER What confuses me is the bridge. It says Z75 will this work with the i5 2500k? or would I have to get a different CPU and will the 660 work with this as well. Sorry for dumb questions just making sure before I make my purchase. Please don't tell me to go with some new CPU like the Icy bride unless I NEED to have that.
