2560 x 1440 vs 1920 x 1080 how big is the fps hit? - Games

So I'm looking to upgrade to 1440p and I'd really like the extra detail on the screen but I don't also want to sacrifice the playability of 1080p. Right now I just have a 24 inch LCD 60 hertz display and I'm on the fence about switching to a 1440p display with a single GTX 1080. My 24 inch LCD 60 hertz display is the best monitor that I've ever seen with my own eyes so I guess that's why I'm on the fence. Any help is appreciated. This is the monitor I've chosen if I end up going to 1440p: ASUS ROG PG279Q Black 27" WQHD IPS 2560X1440, NVIDIA G-Sync Gaming Monitor, 165 Hz refresh Rate, Slim Bezel Design with HDMI USB Ergonomic EyeCare Technology , [url]http://www.newegg.com/Product/Product.aspx?Item=24-236-660[/url]

It's just under twice the amount of pixels so expect your framerate to be halved, assuming you're not cpu-bound.

Most newer games won't let you even get to 120fps at max settings with 1440p. Also this should be in the Hardware section, shouldn't it?

honestly I would say if you play a game at 1080 with fxaa on that's the same FPS you'll get at 1440 with AA off. probably a little more frames than that, but the biggest thing boils down to if you're going to be playing with AA on or with some kind of supersampling

Why the hell are you asking this in a forum when you can literally look at your hardware and then go to anandtech or hardocp or nordic hardware or guru3d and [B]literally[/B] see multipass benchmarks of exactly what the difference will be.:why:

Do you already have a GTX 1080 ? If you have; go to the GPU control panel and turn on Virtual/Dynamic Super Resolution or whatever is it called for Nvidia cards. This will enable you to use 1440p even if you have a 1080p monitor. Then launch a game you want to test in fullscreen and select 1440p resolution and try it out. I have a R9 270x card from 2013 and I recently benchmarked Hitman Absolution using this method. At 1080p I got 50-60fps in outside areas, and at 1440p 30-40fps with 4xAA.
