Asrock z77 Extreme 3 vs Asrock z77 Pro 3

Those are not "cards", they are motherboards. GPUs are referred to as "cards". The extreme 3 is more gamer oriented because it allows for a 2nd GPU to be inserted. The Pro 3 uses different capacitors I think. The Pro 3 has the consumer/professional in mind and the Extreme 3 has the gamer in mind.
 
I have the Extreme 6. I also have the exact same processor. The Bios of the Extreme series has a Overclocking utility which is very easy to use. It has preset stepped incrementals, mine is 4.0, 4.2, 4.4, 4.6 and so on. I stopped at 4.2 and I am using a coolermaster hyper 212 for cooling and I am doing fine.
