You missed two important points: Power consumption for both in real world? (ignore spec. values) VT-d feature missing; only 4770 supports it. This helps when folks running VMs. I reckon 4770 better: price paid + power consumption (not much OC) + less heat factor (?).
I want to render video's but not 3D, is it worth shelling out the money for the unlocked version or not? I have no knowledge really about overclocking processors really.....but standard (without oc) the K version is faster.....
sry bios type fast ^_^
no u cant oc-ed non k auto it must from biso and with someone expert so if u want oc-ing sure 4770k is recommended
i7 4770 is looled better on water then K? 4.674.8 GHz it it true? and how u overclocked non K ? auto?
