I'm getting this monitor and was wondering if my GTX275 would be enough to play games in that resolution. Such as: Fallout: New Vegas, Dragon Age, Far Cry 2, Mass Effect 2, F.E.A.R 2, etc. I would have said FFXIV, but we all know it runs like poo on everything haha! Anyway... I was thinking of upgrading to this. I looked at a few benchmarks to see the difference between the two at that resolution and it seems like it makes a difference, but am I really going to notice it or not?
Basically anything over 20 fps is playable and anything over 40 fps is acceptable. More than that doesn't mean you won't see a difference because there is, but it's not really any significant improvement.
Have you considered overclocking your GPU instead? Rivatuner and EVGA Precision are two really good programs.
