You can't go wrong with a Thermal Right Ultra 120 extreme for better cooling and higher overclocks. I have no personal experience with the 750i FTW but the reviews I have read say that overclocking with that board is pretty simple and runs very stable, taking the same CPU to 3.6ghz. Individual results do vary dependent on the hardware you have, although I am sure that everyone here will assist you in getting the most stable clocks.
