upgrading a sk-6 to slk800... worth it?

i have a thermalright sk6 with thermallake 80mm, 54cfm fan installed diagonally. would i see any noticble temperature drop if i went with a slk800 using the same fan? thanks.

You might see a 3 - 5 degree drop. i would say probably about 3 degrees, mainly because of fan placement. The SLK 800 really benefits from the direct flow fans. Is it worth it in price?

IMO no. I just bought two SK6+'s for 20 bones. Can't go wrong with that.
