Quote:Asrock Z75 Pro 3 is cheaper, yes, but shouldn't I get a Z77 motherboard for overclocking i5 3570k?

Both of them can overclock i5 3570k to 4.2GHz without an issue
Z77 supports multi graphic card ( in SLI or Crossfire ) , Z75 only support 1 graphic card . Z75 would be a better choice if you used no more than 1 graphic card
You can buy i5 3570K for 170$ (60$ cheaper than newegg) here :

Save 60 bucks and get a better mobo . For example :

I would just like to point out that there are some Z75 motherboards that support SLI or Crossfire.
