I recently saw Skyrim running at a solid 60fps. All the games run fine with this card, even bf4 on ULTRA suprisingly. I havn't seen many benchmarks on mmorpgs like GW2 but it's generally known to be better fps(frames/second) then any FPS(first person shooter). I did see a video of a guy playing...
For others who are looking for another answer other then "buy the 7950", which is more suitable to the average budget gamer like myself, I thought i'd add another comment. People still read these threads even though their answered.
I would go with 760 with it not being marginally under the 7950 but being a lot cheaper(419$ compared to 259$). But right now the 660 ti is under 200$ and is the one im considering because its so cheap right now and is about -10% from the 760. I figure i'll have to upgrade to another card later...
