Computer guys: Please help with monitor selection

[CoryM]

Hey guys. Hoping one of the local computer gurus will help.

After spending a couple months on the couch using my TV as my monitor (surgery), my 17" monitor seems a wee bit small......

I'm looking for around 27" single monitor. Card is a GTX 670. I was talking with a guy at the local computer shop and he figured the card was too weak to bother with anything beyond 1920x1080 and 60hz. I'm a little confused because on paper the GTX 670 should be able to handle more(?).

In terms of resolution and framerate with no tearing/stuttering etc, what do you figure the max I should go for? I'm probably not going to upgrade the 670 for a while, but if it makes more sense to buy a more capable monitor for future upgrades, then I will. If it matters, I'd rather run a lower resolution and have smoother display. I do not play FPS competitively and I have a huge list of 3-5yo games to get through before I buy more newer ones so I probably will be fine with a basic monitor.

Thanks for any help.
