I will be overclocking my cpu and will have a controller connected to my computer very often. Once I get a little more money I'll get another 4870 and crossfire them. Is a 1200 watt psu really needed? Also, will that cooler be functional?

not a chance, a quality 750 watt will handle 2 cards fine if you still not comfy get an 850watt instead thats one of the best coolers it will work fine just get the 1366 version
