Opps I thought I'd changed that, fixed now
Well both metro2033 and cyrsis2 are known to run better on nvidia
Both are great examples of badly implemented Tessellation which can bring almost any card to it's knees.
In metro 2033 the gtx560ti easily beats the 6870 and is nipping on the heals of the 6950 (the5870 does only slightly better than the 6870)
In crysis2 the gtx560ti out performs the 6950 and isn't far off the 6970 (with the 5870 slightly behind the 6950)
But overall scores put the gtx560ti in the middle between the 6870 and 6950
Cat you should know about the whole debarkle over the rubbish use of tessellation in crysis2, how only a few objects inconsequential have a rather high level of tessellation applied to them and uses gpu calls that favour nvidia over ati
