Whats the difference between these 2 amd chips?

The 95W version runs at slightly lower voltage and does generate less heat, but the 125W version is close to the bottom of its envelope so the difference in heat is not as much as the 30W difference in spec would lead you to believe, its only about 10-15W but its still significant enough to make the 95W a better choice.
 



Cool. What's the difference between that one and this one? http://www.newegg.com/Product/Product.aspx?Item=N82E16819103674


Haha this is confusing.
 
The 955 that he listed is the C3 stepping, it runs a bit cooler and OC's a bit higher than the C2 stepping that you linked to, and is $5 less ironically. You want the C3 stepping if they are the same price but definitely want it if its going to be cheaper too.
