I'm about to get one of these off of newegg for 340, http://www.newegg.com/app/ViewProductDesc.asp?description=14-102-290&depa=1 , and basing on some of the customer reviews there, i was wondering if the stock cooler will be enough if I'm not planning on overclocking or anything. If not, will it be worth it to spend the extra 30 bucks or so to get the ultimate edition with the zalmans heatsink.
