do some research, measure your case, get some specs on the heatsink. Obviously the first one is a little more high-end, so I'm gonna say it will probaly be more effective. Either that, or it's just prettier.
Personally, I'd get the second cheaper one if you're not planning on oc'ing that thing to hell and back. If you are doin some heavy oc'ing, go ahead and get that first one. If you can save 20 bucks, why not?
