Ok guys, Ive got almost everything planned out now. Really, the only thing I need to settle is what kind of memory I want. The problem that I'm having is that I've heard that the crosshair is picky with it's memory (which doesn't help). Also, I've heard the it can be troublesome to run a second pair of sticks because of (I think) voltage problems. So.. how do these sticks look? Low voltage and pretty good timings.
Otherwise, as far as I know, G.Skill Ripjaw 1600s work just fine in a Crosshair. Your limiting factor will not be the RAM for this board (or the other one I listed), unless you're interested in going for massive RAM overclocks or if you go for really crappy RAM. The Ripjaws are good performers. Not top of the line, but they will not limit you.
