Sure, some games especially older ones will easily hit >60 fps all the time at 1440p on a single top GPU. Newer titles, nope.

GameWorks is a real threat, I've always said that. As for actual HairWorks, it ruins performance for little visual gains so even NV users run with it off, I noted that in the steam forums.
In Dying Light, disabling NV DoF, AMD GPUs run 33% faster. It's a no brainer for AMD gamers to turn that effect off. Project Cars just suck on AMD regardless. Just look at the [H] review where they stack GW titles and GW features to gimp AMD. AMD would actually need to be 25-50% faster and more efficient overall just to compete in such a line-up.
Basically people who use AMD have to play most GW titles a few months after release (once its officially patched up & AMD improve their drivers) to get decent performance (look at FC4, ACU etc now). If you're not OK with that, go with NV GPUs. That's the bottom line.
I'm OK with that personally because A) I rarely play titles on launch, I buy it on a steam sale and B) I'm NOT OK with anti-competitive closed source & code obfuscated GameWorks. But I understand people have different views. The way I see it, AMD is more than competitive because GW features are OFF in my gameplay.
Funny enough, Batman: AK which has 4-5 GW features, seems to run just fine on AMD, not sure what happened there!!
