I'm getting a PC from pcspecialist.co.uk and I'm not sure which CPU to get, i7-4770, i5-4670K or i5-4670, if I got the i7 I would have to get a crappy monitor! Also, I'm not sure if pcspecialist PRE-overclock it, because I don't know how to. I'll be playing games like DayZ, H1Z1 and BF4! PLEASE HELP!
