Aight, I swapped the 4570 + H87 for a 4670K + Z87 combo. Was about 30€ more expensive, but hell, who cares. Going stock for a while, and overclocking a bit later. Here I come, DayZ!
Truth be told, I'm a universty student and sporting a pretty tight budget. The system I bought was quite exactly 600€ and can't go up much more. I would most likely have to change the mobo too, because I ordered an ASRock H87 Pro4 (no overclocking if Non-Z OC doesn't work anymore). What if I wait a few years and update the processor? Or will the socket be obsolete by then?
That CPU is "locked", so can't overclock. 4670K (unlocked) is around 20€ more expensive than the 4570, with a stock clock speed of 3,4GHz. Should I go for that instead?
