I am looking forward to buy a new PC. I earlier chosen 6700k. then after the arrival of 7th genration, I was looking forward to buy 7700k. But I saw over the internet that ,i7 7700k, heats up too much , it easily exceeds 60-70 degree celcius. I don't want to spend too much on cooler, may be I can buy cooler master 212x . should I choose 6700k ?
