Are the G.SKILL F3-10666CL7D-4GBRH Ripjaws the best value memory to use with the i5 750? I'm not looking for the highest possible overclock with air cooling. I'm just hoping to get a decent 750, RAM, and mobo that will get me a 4ghz oc. Are there certain steppings that I should be looking out for with the i5 750?
