No one dismissed the 960 entirely I said the 960 would be fine :/ from what I read people said they pushed the pentium to 4.2 but that was the maximum they could get with the stock cooler without overheating. Getting a better cooler to overclock wouldn't hurt, he is putting the computer in a smaller case so the airflow won't be that great people who got high clocks with the stock cooler also had bigger and well ventilated systems.
