I have decided to buy a radeon 7870 and I'm choosing between Sapphire's 7870 (non OC) and gigabyte's 7870. With which one would you have gone ? And also the gigabyte cost me roughly 20€ more... (300-320€)
I don't think if the Gigabyte is worth it for the €20 more. I wouldn't recommend to buy one of the same graphics card that costs €20 than the other, except if the more expensive one has really good cooler like Twin Frozer III Direct CU II, etc.
