Can ATI Radeon 5870 run 2560x1440 resolution playing games?

Hi, I'm looking to buy a new monitor and am trying to decide if it is worth the investment to get a 27" monitor at 2560x1440 resolution (like a Dell U2711, ~750-900$) or stay economical and get a 23" 1920x1028 (U2312HM, ~240$).

My main concern is if my ATI Radeon HD 5870 can handle displaying 2560x1440 in games. I believe it only has 1 Gb of vram, though I'm not sure. On top of that could it still run a 1920x1028 side monitor?

If I can't take advantage of the amazing resolution it makes my decision very simple, but I'm no expert on this material so I wanted to check here first before I settle on the 23".

Thanks in advance!

I bought a Korean 27" IPS 2560x1440 monitor on eBay for $300. I have a 5870, an i7 2600 and 16gb of RAM. I can play games at 2560x1440 but not with all setting maxed. I can run most games at high but not ultra or extreme (if there is an option for that) around 40+ fps. Hope this helps!

The 27" Korean IPS monitor is the best computer investment I've ever made.

It can, but if the game is new, you might experience low frame rates due to the 1GB of VRAm. Some new games don't use much vram are fine with 1GB even at that resolution.

If you start turning up anti-aliasing, and anisotropic filtering, etc, you might also notice the performance will drop.

Although not the most elegant solution, you can always set your game to exactly half the resolution of the monitor (so the pixels are quad binned), and turn up the anti-aliasing to get a nice picture. With a 27" monitor, you are not hunching forward on the desk anyways, so it will not be too noticeable.

I've heard about these monitors, is it LED backlit ? How's the build quality ?

It's LED - in fact, the panel is supposed to be almost identical to the panel in Apple's 27" Cinema display. The build quality is what you'd expect from a bargain monitor. It's similar to a low-tier US monitor. My 24" Dell and 27" 1080P Samsung screens have much nicer bezels but they simply can't compete with the Korean screen. The screen I got had no dead or stuck pixels and the stand is solid enough that I don't think it will be an issue during its lifespan.

Is the build quality as nice as a $900 Dell 27" IPS monitor? That's a definite no. Is it a bargain at $300 shipped? Absolutely.

I hear ya... Next time I need a monitor, I'll look into these. Thanks!

Oh, and, I run 3 screens total: a 27" 2560x1440 Korean screen, a 1920x1080 27" Samsung, and a 24" 1920x1080 Dell monitor for audio production purposes. You should be able to do the same on your 5870. Regarding the initial question, my answer up top is a real world answer. You can expect decent frame rates (I get around 80fps on Starcraft II and always over 40 on more graphics intensive games) at high detail @ 2560x1440 res with your setup which is similar to mine.
