i just purchased a new one here is the model i got.
BenQ GW2760HS 27" Widescreen LED Flicker-FREE Slim Bezel Monitor - Black
what do you think?
My 120Hz monitor is a BenQ - it's a bloody wonderful monitor, and every BenQ that I've used has been fantastic. That being said, I only have experience with their high end monitors.
I've never tried their flicker free models, mostly because I particularly WANT the flicker of lightboost2 for playing at high refresh rates.
It's pretty cool that it's an AMVA panel; you don't see those very often, and they're good. Very nice mix between the color accuracy of an IPS and the speed of a TN. The only downside of that panel is that the response time is "all the way up to" 4ms (still totally unnoticeable), and that it's only 60Hz. BenQ has the best 120Hz panels out there, but since this is a completely different panel type... I've never even seen an AMVA running at 120Hz, I don't think.
That being said, now that we're past me nerding out about the monitor, there's no reason for you to get a 780. My GTX 670 gives me more than acceptable performance at either 1080p, 120Hz, or at 1440p, 60Hz. At 1080p and 60Hz, well... it's a shame there's no 760 ti yet, since it's going to be a rebranded 670 for less money...
The 760 isn't going to be quite enough performance to be worth the upgrade, but a 770 will set you up beautifully for your monitor, at quite a bit less than a 780. You'll be able to wipe the floor with pretty much any game except perhaps Crysis 3 or Watchdogs... the first because it's got some odd requirements for a graphics card, and the second because it's very poorly coded.
