Hi. I've been looking to update my mb and both of these have grabbed my attention. I us my machine mainly for gaming and video converting and I'm after a mb that can easily oc my phenom 555be. Both of these mb tick all the boxes. There is a bit of a price diiference between them and is the Crosshair worth the extra. I have a 1tb hd and a GTX460 and 4gb ram (which will be bought when i choose the mb). Any advice would be appreciated
