We often use the term “super cooler” in our reviews to denote the most efficient air-based cooling system that is capable of handling an overclocked CPU without producing much noise. But after our tests of the exquisite Sapphire Radeon HD 6950 2GB Toxic Edition we are now thinking whether we should introduce the term “super graphics card” which would denote a product with unprecedented performance and unique features. We think we really need such a term because we've got yet another graphics card that claims to be super. It's Gigabyte's GeForce GTX 580 1.5GB SuperOverclock.
