Ok, so i am going to buy a CPU off amazon UK so i was researching the newest I7 4790k. I was hearing that the L3 are the old ones and they aren't as good overclockers as the L4 which came out in 2014. The thing is the batch number on the 4790k of amazon is a L3, should i stick to a 4770k or should i get the L3 4790k ?
