Just want to know whats the best for gaming.
The ASrock Z77 Professional, the P67 Professional (B3), the Z68 Professional Gen3 or the Z77 Extreme 6.
Also dont know whats the difference of chipsets.

Z77 has support for pci-e 3.0 with ivy bridge cpus only. The other two chipsets may support ivy bridge with a bios update. Not much difference in speed; overclocking depends on the board bios adjustments. Newegg is closing out some evga boards with the older chipsets for around $50, a good deal if you don't plan on running ivy bridge cpus. The boards don't support the newer cpus; hence the low price.
