I am in need of a new motherboard I don't really want to upgrade everything jsut the Mb for now I am an using ivy bridge cpu and the Z77 chipset is what I would need. I think it is the best chipset for the 1155 socket for me. my question is what is the big difference between the P8Z77 V-PRO and the Z77 Sabertooth MB. They have very similar specs. They both have PCI-e lanes in pretty much the same spots at the same bandwidhs i think i could be wrong about that. But I know the sabertooth has 1 PCI_e 3.0@16x and another at 8x and then the third is a PCI-e 2.0 so I would hope that the V-PRO is the same. but other than the price how does the V-Pro stack up against the sabertooth and would the extra 40 bucks be worth it????
