Super clocked, super fast, super quiet!
For testing the Gigabyte N560SO I have used our regular testbed, which comprises of an Intel Core i7-2600K, Kingston HyperX T1 4GB DDR3-2200MHz memory, Gigabyte P67A-UD7 motherboard, Kingston V-Series 64GB SSD with Windows 7 Ultimate running on it; all of which is powered by a Cooler Master 1200W Silent Pro Gold PSU. For comparisons I have added the Zotac GTX 570, the MSI R6950 as well as the R6870.
As you can see the Gigabyte N560SO is fast enough to touch the heels of a standard GTX 570 as well as outperforming the HD 6950 in some cases. Obviously a stock HD 6870 is no match for this overclocked beast.
