I went 27" as I also wanted to get rid of my 32" TV without loosing too much size and not having to pay a small fortune for a 30" ips monitor. I only paid $300 for my shimian and it was money well spent for sure. I only have a 560ti, and while it seems to be ok on most games it only have 1GB of vram and I was spotting some more pop in than before on some newer games I tested out. I was thinking about upgrading gpu before I got this monitor anyway. If it comes to playable fps or eye candy, of course I will turn some of it down or off as needed. Though if I can have both... why the hell not?
The thing I was most concerned about was how bad SD movies would look full screened on such a high res, but it doesn't seem to be that bad at all. I have a lot of films that seem to have been ignored by the blu ray generation thus far. Well... sh*t some of them are even LD transfers for that matter.
