Re: Which Processor + Board
From what I gather, if you aren't going to OC, then the stock cooler will be sufficient. I picked up the Sunbeam Core Contact Freezer which comes with TX-2 thermal paste. It was only about $40, and now has a $10 MIR from New Egg.
Edit: Although I am not sure if it would fit your case. Totally uo to you and your requirements/budget.
