boredgunnerBetween those four options, I'd get the U2713HM for the larger resolution which will really benefit gaming and image editing.

Cheers, that's what I was hoping? (or should that be afraid of? )
 

boredgunner8ms might seem high, but at 60 Hz the difference won't be big compared to a lower response time.

My current screen's an 8ms GTG panel, and I don't have a problem with it playing UT, etc.  Other than at work, I've never used a TN panel ...
 

boredgunnerIf you're willing to branch out from those four choices, check out the Overlord Tempest X270 models.

From what I can see, they're not available in the UK..? (my Google-fu failed to find a supplier, anyway)  To be honest, the reason why I'm looking at Dell is that they're the same price as or cheaper than equivalent Iiyama, Asus, NEC et al, but they have a 0 dead pixel guarantee.  The 3 year warranty is a plus, and those we've got a work just tend to go on without problem.

boredgunnerTo be honest, I recommend the GTX 970 regardless of your monitor choice, since it's more "future proof" and modded S.T.A.L.K.E.R. + supersampling would benefit from the added power even at 1080p.

Yeah, it's obviously the best value card ... I just have a "problem" parting with nearly £300 on a graphics card.   I was hoping nVidia would have released the GTX 960 by now, as I feel that would probably be the best board for me, but that doesn't seem to have happened...
 

boredgunner As a side note, Bioshock isn't really a "slow" FPS.  

Ah, I thought it was a lot less "twitchy" than UT, multiplayer CoD, etc..?  Can't say it matters much, though.

Cheers - those are the ones I was leaning towards.
 
I guess I'm going to have a "fun" evening with a tape measure trying to work out just how much of a squeeze the U2713HM is going to be...

XrayManThe more real estate to watch it on, the better.     =)

Heh, true.   I've settled on the 27" one, as it will just fit, and the extra screen space will be useful for image editing.  Now I just need to pluck up the courage to actually order it ...

Well, the U2713HM is a lovely screen, but Dell seem to have a QC issue with the the production of it - I went through 3, and all of them had fine scratches in the anti-glare coating near to the bezel (it looks like the screen was wiped with a less-than-clean cloth at the end of the assembly process).  They weren't really visible under dim lighting (i.e. overcast English winter weather, or artificial light), but get direct sunlight on them and they lit up - even with the screen in use, you could see the "thicker" parts of the scratch as a "shiny" speck.  To add insult to injury, none of them were supplied with the right power leads either (the monitor needs a lead with 3 holes for the "kettle" end, and we have 3-pin plugs here - all of them came with a lead with 2 pins for the socket and 3 holes at the kettle end, and 3 pins for the socket and 2 holes at the kettle end - if you cut them in half and mix-and-matched them, you'd have been OK!) ...
 
I'm not sure if this is an end-of-run QC issue (the U2713HM was replaced with the U2715H about 2 weeks after I got mine, typically), Dell's QC generally having a "funny 5 minutes", or what - my parents have a Dell P2414H bought in January which is perfect, and Dell's monitors have an excellent reputation normally.  I'm now not sure if it's worth looking at the Dell U2715H when reviews are out, the upcoming U2515H (25" 2560x1440), or looking at a different brand like Iiyama (the XB2779QS looks lovely, although I'm not sure if it's going to be too reflective), or Eizo (if they release a replacement to the EV2736W that's like the EV2450, it should be fantastic) - whilst they all use the same/similar panels, neither of these have the excellent "0 bright pixel" warranty Dell offers, although Eizo offers a 5 year warranty and tighter factory calibration...
 
Have to say, going 2560x1440 was an interesting experience - a fantastic amount of screen space for photo-editing (Lightroom does seem to gobble a fair few pixels), and FarCry 2 & This War of Mine looked great, but, combined with the large physical dimensions, for normal office use it felt a bit over-sized..! (maybe that's me needing to adjust to it)
