Benchmarks I received a few hundred point alone from the upgrade. My last (Temporary board) was the Asus P8Z68 V-Pro Gen 3. After upgrading to this board... I received my few extra hundred points. Now from what I read Gen 3 X16/X16 will have the most effect @ higher resolutions.
But the other good news I want to mention is if you go 3 way sli in the future or add another type of expansion card...... the other two slots run @ x8/x8. So if you have all 4 slots running you will run like X16/X16/X8/X8.
Not to mention that if your running benchmarks and you don't like the score you got..... well then you will know for sure it is not because of you loosing bandwidth.
The other area you are missing when it comes to the difference between the boards is the type of components used to make them. The ASrock board.... is more of a middle grade board. It is made with components that reflect that. (The number and type of Mofsets exc....) These types of things will allow the Gigabyte board to most likely sustain a higher overclock longer then the ASrock board you are looking at. (12 Digital Phase vs 8 Digital Phase)
The Gigabyte board is made with better components and more of them. (The number and type of Mofsets exc....) As well components like the "Killer Onboard NIC card" Also like the Onboard " Creative Sound Blaster Card "
Plus there is more.... here compare the two..... Gigabyte Sniper 3
Asrock Extreme 4 Z77
If you look it over .... you will be able to see a lot of extras a differences that will shout out at you. Now if you choose to save some money because you don't need most of that stuff. That is understandable..... but it seems you are thinking about building a hell of a rig. My idea for that is why not get the best backbone you can for your highend hardware to run on.
