ok thanks for the links. So I misunderstood, it's chipset what I am talking about.
I am confused on the wikipedia article it says Z77 Panther Point "8 PCI-E 2.0."
Asrock Z77 Extreme 4 which I read is the most popular board right now, only 6 PCI slot. But it's 2 PCI-Express 3.0, 2 PCI-Express, and 2 PCI. So only 6?
So what does it mean on the wikipedia "8 PCI-E 2.0." Depending on manufacturer it can have up to 8? But what is the 2.0? All new z77 boards should have 3.0 right?
Also confuse on B75 vs H77 looking at wikipedia article.
B75 looks to be smaller Micro board than H77. But B75 can be overclocked?
On the other article you link me it says H77 cannot be overclocked.
B75 has only 2 dimm slot and 1 sata 3, but processors used with it can overclock?
H77 has more dimm as you says and more sata 3, but cannot be unlocked?
So why would you go H77 ?
