I haven't actually checked, is there the "cheap" version of the 27" screen?
The 23 " 700D is all but identical to the 750D, dvi instead of displayport(both have hdmi) and a "normal" stand rather than the lump on the 750d, but same screen, tech, everything else.
For 2d it's fantastic, I'm not sure how up there it is with IPS panels these days, its better than my pretty old IPS and leagues ahead of my not that old TN screen. It's gorgeous, I'm AMD though, I've had it for 2 months or so and barely used 3d. Whacked on a few films, meh, still haven't tried gaming as honestly I just don't feel the urge to and keep forgetting to sort it out
Anyway the 23" versions the 700d is £100 cheaper than the 750d, for all but identical screens its quite laughable, if there was a 27" 700D, I'd recommend that. I'd also say, as PCM2, buy it for 2d, you might like 3d, you might love 3d, you might hate 3d. Even if you love 3d most of the content you can watch or play will either be 2d only, or 3d won't work well with certain games. Think of 3d as a bonus on top of a truly excellent 2d screen.
