SSE4.1 is only useful for newer encoding software. It does nothing for games and everything that aren't coded to take advantage of it. He's not going to get 4.322ghz oc on that motherboard. And Intel stock cooling is not good enough for oc, no matter what they say.
70 euros for basically nothing.
I was totally kidding about SSE4 hence the ";)"
And of course the OC he will get may be lower, I'm just pointing out the possibilities with it. I had a 1200mhz OC on my old E2160 using the cheaper all aluminum Intel HSF, several of my friends all run @ 3ghz with the stock cooler on their E2160s.
