i am looking to get this motherboard here http://www.newegg.com/Product/Product.aspx?Item=N82E16813131767
and i was going to get an amd phenom ii x4 955 black edition and then upgrade when the new bulldozer am3+ comes out ( future proofing ) anyway so i was wondering if the stock heatsink that comes with the processor will mount to the motherboard.
The last time AMD changed their heatsink mounting pattern was in 2003-2004 when they moved from the spring-clip Socket A heatsink to the cam-lock 3.5" pitch Socket 754 and 940. AMD has used that same cam-lock heatsink for all desktop CPUs made since that time period and many server CPUs as well. It's a good design and I don't see AMD moving away from it any time soon. The fact that they're continuing to use it on their FM1 parts is very suggestive that they're sticking with that heatsink for a good long while.
Also, Socket AM3+ is physically identical in size to Socket AM3. It merely has slightly larger pin holes and a few minor electrical differences compared to AM3. It uses the exact same heatsinks as AM3.
