GTX 670 2GB enough for 2560x1440 ?

post #1 of 6
Thread Starter 
I am thinking of getting a new 27" TFT screen with a 2560x1440 resolution since I want to invest my money in something that lasts at bit longer this time around. Usually I upgrade graphics card every year but last time I upgraded I felt it was bit of a waste going from 3x GTX 580 1.5GB to 3x GTX 670 2GB, since the boost was mediocre and the performance from the GTX 580's was still good. So before I end up with another bad decision I just want to ask for first hand experience.

Is 2GB enough for gaming at 2560x1440 resolution ? or is it a bad idea ? I wondered if I should get my GTX 670 2GB upgraded to GTX 670 4GB cards before making the move to 2560x1440.

I play at max settings and usually with 4x/8x Anti-Aliasing, but I'm willing to use FXAA or 2xAA at 2560x1440 it that will be acceptable.

I have a 4½ year old Asus VW266H 26" TFT 1920x1200 that is still superb, but I am thinking up getting a Asus PB278Q 27" TFT 2560x1440.

It is enough alright. Either way, the 4Gb model is stupidly expensive for what it is that I would not throw my money at one.

Turn down the AA and you'll be ok, for now.

Don't go for the 4gb 670s option, it's a waste.

Another option I'd go for if it was me is sell your 670s for $300 each and buy two gtx 780s.

Two 780s are perfect for 1440p. But I think you'll be fine as is with your set up.

That would be fine if I had the cash smile.gif unfortunately that's way too much for me to spend smile.gif

I'll go with the 2560x1440 screen now, and then I'll upgrade graphics card when perhaps GTX 780 is further down in price later this year or more likely wait till Maxwell in 2014 wink.gif

Tri-SLI 670s is more than enough graphics horsepower for a single 1440p display. If you are able to overclock to just 1200core and 6600mem, you should be outperforming stock 680s.

As for the VRAM, the increase in resolution is not enough to cause any problems, but rather it's AA thatwill chew tthrough the graphics memory.

That said, I find that the higher resolution of the 1440p and 1600p screens actually cuts the need for AA in half or so. I usually run 8xAA @ 1080p, but I have never felt like I needed more than a max of 4xAA @ 1440p, and I usually run FXAA and can't really tell much difference.

I am pretty confident that you can run ANY game @ max settings with FXAA or 2-4xAA without issue. Also, you will find the image quality to be a significant amount better even without 8 or 16xAA.

The more pixels, the less need for anti-aliasing. I would still max out AF because it doesn't have hardly any performance penalty, and with the sharper screen you will notice shimmering textures.

Wednesday I got a new screen, the Asus PB278Q 2560x1440, 60Hz, 5ms, PLS panel, 100% sRGB colours. After using it for a few days I just wanted to give a short overview of my impressions with the screen.

It comes with Dual Link DVI,VGA,Display port, HDMI and speaker connection. It can be raised and lowere and has pivot/tilt function as well as it can be rotated to portrait mode. The screen base is heavy and sturdy and won't fall/tip over when you rotate the screen.

There is an ocean of different screen settings, but it comes with 5 presets to choose from and the of course the option of user defined settings.
Actually the only setting I changed right out of the box, was the TraceFree setting (more upon that later).

My 4 year old reliable Asus VW266H 26"TFT 1920x1200, 60Hz, 2ms I thought need an upgrade and worthy successor, so I dediced to move up in pixel class to challenge the graphics cards and get a better image quality with a higher pixel density. So instead of buying GTX 780 3GB SLi for a 1920x1200 resolution, I invested in the "future" for 2560x1440 resolution, and the the GPU power will have to wait till it's actually needed in this resolution.

There is almost 75% more pixels going from 1920x1200 to 2560x1440 and it quite more GPU demanding. In Unigine Heaven 4.0 benchmark with everything set at på max the FPS difference was 1920x1200/84FPS vs 2560x1440/55FPS - a whooping 29 FPS difference !.
With that said then wow what a picture quality you're rewarded with. It's so detailed and sharp because of the better pixel density.

One thing that may cause concern many is input lag, ghosting, overshootand the fact it's "only" 60Hz.
Last thing first. It's 60Hz but I'd gladly sacrifice 120Hz in favour of more pixels and a sharper image than e.g 1920x1080 120Hz screens.
The screen has an option called "TraceFree". Per standard it's set to 60, but for gaming 20 or 40 is recommended. I've set it to TraceFree 20 and I can't tell any difference between input lag, ghosting/overshoot going from the Asus VW266H to the Asus PB278Q when playing First Person Shooters like HomeFront & CODMW2. What I primarily noticed was the slightly larger viewing area (26 vs 27), but the difference in sharpness was evident. The picture is more immersive and rich somehow - it's hard to describe, so you really need to see it for yourself.

Background bleeding or pixel error I have not seen anywhere on the screen.

So if you're looking for a fairly budget friendly screen with 2560x1440 resolution which is suitable for games like First Person Shooters, then I'll highly recommend Asus P278Q.
I expect mine to last at least another 4 years before considering an "upgrade". biggrin.gif
