Well the link you posted for the Sapphire card claiming 7000mgz gddr5 ram, seems that's a lie, from what i can tell its on a 256bit memory bus and i doubt GDDR5 runs that fast seeing as its not that much different from what DDR3 is from my research.
Funny its only 256bit bus, video card im using is 10 years old if not older and its memory bus is 256bit as well and uses Gddr3 ram.
As you can see from the pic not 7000mgz as well i don't know if Sapphire still makes trash video cards but many many years ago they use to only pump out trash from what i remember, don't know if that's still the case.
As well the fastest DDR3 ram out their is 266mgz just so you know so GDDR5 isn't even 1750mgz its probably 4x times slower then that meaning 400mgz at best and i don't care about Bus I/O speed that's not memory speed, and real world benchmarks never end up being what the white paper maximums are, just look at the peek speed of what USB2 is vs real world speed.
As for what card to take, did some research on the topic and they kind of look the same.
My self id take the Gigabyte card cus i don't like the other guys, they use to make trash way back when.
Core clock of 1% difference changes nothing in my world, nothing overclocking won't fix.
