Right now I'm trying to decide just what to do about a monitor. I had been looking at getting the ASUS VE247h (which I still think I'll most likely get) but 1440p seems interesting. I'm gonna have a 4670k and a gtx 770 in my system. My system is pretty powerful, but it isn't the best possible. Would 1440p even be worth it without at least a 780? I really don't want to spend more money, so is the quality on a 1440p really even worth the extra $$$$ I'd have to spend? This is a gaming rig, so that's what my time is gonna go into. I don't care about super high quality movies and all that junk, I just wanna game and surf the web really. So I guess to sum up it up in one question, is a 1440p monitor worth the extra money for the monitor itself and (potentially) a more powerful GPU setup? Just for information purposes, I'm not rolling in it. I'm a teen and I work with my dad during the summers to save up a little bit of money.
Considering I can run all my games really well at max settings at 1440p on my 680GTX -- you will be fine with the 770...
Honestly man, you spend a LOT of money for the final result of what you see... I've seen guys spend $2000 on a wonderful computer and skimp and get some 20in non-1080p scale monitor. It blows my mind.
To me, the difference between 1440p and 1080p is HUGE. If there's anything you should skimp on when building a gaming PC, it's not the monitor. There are some fantastic deals out there. Keep looking til you find one in a price range you are willing to spend.
Your card has more than enough power to run 1440P on high settings (but not ultra/max settings) with most games. I have a 27" asus pb278q i picked up for $600. IMO, its totally worth it if you play an MMO (Eve for example), and its not bad for FPS either. I can run Far Cry 3 on medium settings at 1440p on my single 580GTX, if i wanna max it out ill start getting fps drops. For Deus ex human revolution, i can max everything out with zero problems. It's definitely a big difference compared to 1080p. I plan to grab a 780GTX in the near future, but my 580 has been fine for the last 6 months with this monitor on most games.
I was in the same situation and initially thought I wouldn't have the GPU grunt to power 1440p at decent frame rates (I only have a GTX 570)... so I got myself a 1920 x 1200 24 inch monitor... it was great, but there was something niggling me that I should have gone for a larger screen & 1440p though, so I ended up returning the 24 inch & going for a Asus PB278Q... and boy am I pleased I did!
Everything looks amazing in 1440p @27 inches.. from games to just browsing the web!
I was previously running BF3 on Ultra at 1920 x 1200 & averaging around 55 fps, but I am now running at 1440p with AA off & settings down to Medium and it STILL looks better than everything on Ultra at a lower res (to me anyway!)... admittedly I've dropped down to 40 FPS on average, but to me the extra clarity & sharp image is worth it.
So I'd say that if you have a 770 then you'll be able to run most games at respectable frame rates maxed out, with perhaps turning off AA in more powerful games such as Crysis... but IMO 1440P is well, well worth it - BF3 to me just looks like sex on legs at that res even with medium settings :-)
