1. Only the socket is soldered to the board, the cpu is removable.
2. the existing cpu is 35w would replace with a 35w
3. I've run 3 different cpu on that board without issue, a celeron, a 1st gen i5 and a 2nd gen i5.
4. doesn't have to be a 3610. I want to upgrade to a 3rd gen i5 processor, just not sure of compatibility.
thanks
