seems to be the case, albeit there is a gaming mode preset that reduces the input latency from class 2 to class 1, Also responsiveness seems to be respectable for IPS; but the issue remaining is in regards to an aggressive overshooting solution used without any option to disable it. But i need to review it in person before a final conclusion   later this week.

There's been doubt for it even as casual gaming because of the reported overshooting issues, even after a few revisions.
Looking at the U2713HM review
http://www.tftcentral.co.uk/reviews/dell_u2713hm.htm
Seems it's similar to the U2414 without the back light bleed issues, and is 27''. But it seems to have higher latency input of 22.2 ms putting it into class 2, which is 2 frames loss. This is worse than the U2414 in that aspect. Also i don't necessarily think bigger is better. Because i'm using it as desktop monitor so i will be sitting close to it. Everytime you go bigger, your suppose to be sitting further and further away. my desktop table top and my space isn't big enough for that size, or even multi monitor setups. I've found that 24'' works great for me, also with 16:10 because outside of gaming/movies i like the vertical retail space when browsing the web etc..... the black bars never really bothered me.

besides, bigger sized reso will tax your graphics card more, and affect frame rates per sec. You then end up having to invest in a multi gpu setup either SLI or crossfire; then you got to contend with issues with multi gpu setups which usually are very dependent on driver updates to profile games to work well under multi gpu conditions ..... not to mention this sort of solution is much more costlier than a single gpu solution.

It's really a subjective matter whether you prefer 16:10 or 16:9; which i prefer the former. same for 24'' vs 27'' but i personally don't like my 1080p content to be scaled on a higher reso, cause the image quality looks less sharp. Also bigger screen has bigger dot pitch .... with these factors added together, it makes less sense for me moving up from 24'' because of the distance which i will be viewing the content

Just seems to be that if you can get by with minor bleed on U2414, that would probably be better than the U2713. Or maybe the newer Eizo FS2434 which is similar to U2414, will have no back light bleed hopefully. Have to wait for reviews to confirm. Heard there will be reviews out within a week or 2 from now for it. U2414 would had been perfect if they solve the bleeding issues in a future revision; the same could be said for u2413 if overshoot issues had been resolved  some option to be able to lower the brightness to work in darker environments would be much appreciated as well.
