Gigabyte GTX560Ti 448 Core Review
3D Mark 11
At stock it's a league ahead of the standard 560Ti, but the overclock, whilst impressive, ends up only a single point ahead in the Extreme test.
3D Mark Vantage
In Vantage we again find the card at stock settings beating out the standard model, but the overclock doesn't come anywhere near to the overclocked standard card.
