Crysis 3
Crysis 3 is a beautiful-looking game that continues to tax high-end systems. We've FRAPS'd a 30-second section near the start of the game, with lashing rain, numerous reflections and full DX11 pomp on show.
GTX 650 Ti finds it difficult to cut it at the full-HD resolution; the game does indeed feel 'sticky' at points. There's no such apparent problem for the Boost version.
Performance is practically identical to the HD 7850's and way above the GTX 650 Ti's. Again, though, there's no clear benefit of that 2GB on-board memory - and if any game was going to show it up it would be Crysis 3, you would surmise.
