Today I have got a fake intel core i7-4770k. I have got it from taobao and I hope I can change it.
The box is completelly the same as intel's, it probably was taken from a used core i7, but the cpu is a fake. Here are some pictures of the fake cpu.
And this is how real core i7-4770k looks like
If you buy a cpu from an online store, be sure that it is real before you open the box. Cheers.
