Best CPU + Mobo under 300 euros (no overclocking intended)

[DistortionGamer]

I am looking to buy a new processor along with a mobo, after much thought and being told by my older brother that I should not overclock, I decided to follow that advice to minimize the risks.
I want a CPU which will improve my performance just as much as the i5-3570k, except since it's not intended for overclock, I guess it'll be cheaper and a motherboard to run.
I am aware of the i5-3570, but I read that if I'm not gonna buy the 3570k, the 3570 is useless and that I should get a 2500 or a 3470.
Can you please recommend me a CPU and a Mobo under 300 euros, not intended for overclock?

You can still get 3570K and Z77 below 300euro.

Cheaper Z77 boards down to around 75euro can also be found.

You dont have to. you dont need Z77 either. You can do with B75 for example for 50euro. The non K 3570 is 20 euros cheaper. So total price for 3570+B75 would be around 235euro.
