I'm going to be building a new build using a i5-2500K, and I'm thinking about using either of these different kinds of RAM: http://www.newegg.com/Product/Product.aspx?Item=N82E16820231427&cm_re=ripjaws_x_sandy_bridge-_-20-231-427-_-Product or this: http://www.newegg.com/Product/Product.aspx?Item=N82E16820231430&cm_re=g.skill_ripjaws_x_sandy_bridge-_-20-231-430-_-Product If I bought one of those, would it work with a Gigabyte P67A-UD4? And if so, which one is better?
