ok, the fx53 and 4k+ teh 4k runs cooler and is a bit more efficient teh fx 53/55 is leaning more towards total gaming, and really, imho, for vid editing and what not, u should get a p4 system, so if u need to, u could ezily run several vid editing programs or whatever, also 2 gigs of ram is good, the gfx card zen recommended is THE BEST, and if ur not OCing u dun really need water cooling, but if u decide to go with p4 get it anyways, cuz p4's run really hot. anyways, lol zen, i kno ur gonna hate it, but figure up a p4 system too, so he has a couple things to choose from since hes not gaming and it sounds like he might be doing several things at the same time
