From 2560 x 1440 to 2560 x 1600, big difference in GPU requirements?

Hi!

I now have a HP ZR2740W monitor capable of 2560 x 1440 and it looks pretty sharp for games. My graphics card is a single Sapphire Radeon HD6870 1 GIG VRAM.

I can run most games with satisfactory FPS (including recent games like Skyrim & Deus Ex: Human Revolution) in 2560 x 1440. Does that mean I will be able to handle the same games in the 30" res (2560x1600) with an acceptable frame rate?
 
I have an HD 6870. It is exceptionally strong @ 1080p, which is my resolution.

However, at such higher resolutions like yours, you really need a faster GPU, or perhaps better yet, HD 6870 in Crossfire.
 
Overall it felt very similar with movements/smoothness in the games I play, which are mostly FPS games. I went from a U3011 to a ACD

It's probably the same feel going going 1080/1200
 
What is your acceptable frame rate first? That's a diff of 400k. Like for me acceptable is 60+ on most games.
 
if i moved to 2560x1600 id get 2 7970's, because i like max settings and 45+ fps.

To be honest you would probably be able to get by with 1 7970 or 2 7950's if you had to. You can max out (minus max AA) majority of games, excluding a few.

This. At 2560x1600 a Radeon HD 7970 is enough most of the time. These days the only thing high end GPUs struggle with is multimonitor resolutions.

Pffft. For something like Skyrim, I was running High/Ultra settings @ 5300x1050 with a single 6850 and SkyBoost. 5300x1050 is 5.5 megapixel, the OP is only wanting 3.5-4megapixel. Skyrim specifically is very non-demanding in GPU load. No need for even a single 7970 for Skyrim forget about needing crossfire.

Can't speak for Deus Ex.
 
I run a single 2560x1440 monitor with a single 7970. It works great.

In order to maintain 60+ fps, I do have to lower some settings in certain games, but it affects the image quality very little.

Usually AA and SSAO are the first ones to go. Also, I never enable motion blur or depth of field in any game regardless of performance.

We are really at a point where a single high end graphics card can drive 2560 very well.
 
Its a 10% increase in pixels, so I would expect some performance being needed.
 
2560x1440 has 90% of the pixels of 2560x1600, but 1440 is also a wider FOV and that means higher load. This basically causes performance to be a wash between the two, I'd actually lean towards the wider FOV making a bigger impact on performance, so 2560x1600 may be faster.
 
Im running 2560x1440 with two 6870's and as long as you can keep the cards within their frame buffer, they are just fine, its all about just playing with the settings and finding what works for your eyes. Id say pick up another 6870 for now if youre strapped for cash, or if you dont want to go Crossfire, find a used 6950 or 70 the 2gb buffer allows you to crank up the quality.
