yes, the SLK800 is good, but i personally dont like how you have to attach the feet on it *shrugs*
Still its very good, especially with a variable speed fan like the TT smartfan2.
Some other extreemly good coolers are:
Swiftech MCX-462+
Alpha pal8045
Volcano7+
AX-7.
But they are all overkill if you dont plan on overclocking.
If you just want to run at stock, use the stock cooler or something like the volcano 9.
