Could anyone tell me the main point of difference between B75, H77 and Z77?
I know you're able to overclock on Z77s, and not on B75, can you overclock on H77?
Are they all available in ATX and Micro ATX forms?
The H77 is for none overclocking processors like the i3 or the i5 3570. This can save you money if you aren't looking into overclocking. Available in mini Itx, Micro ATX, ATX
The Z77 is for the overclocking and the enthusiast that wants to get the most out of there PC. If you want the best in the LGA 1155 socket this will be you chipset.
The b75 is for business orientate Pc. Lower Memory clocks and no overclocking. you are better off getting the h77 over the b75
I'm getting the Z77 as I will be overclocking, but concurrently building up a spec for a mate who won't and was confused between the B75 and H77.
Will have a H77 for him, thanks again!
