Questions about CoD on 1440x2560 displays

[SharpeXB]

I’m considering upgrading to a 1440x2560 monitor, questions I have are:
Graphics card. Is there a card or combination of them (SLI) that can run CoD at this resolution and full settings? I’m sure I’d need SLI, does CoD support this?
A solution for running a single card might be to just run the games at 1920x1080 and let the monitor upscale them. That might by itself look pretty good. Obviously native output 1440x2560 would be better, just it would be more demanding.
I suppose if you’re running high resolutions that anti-aliasing is no longer needed or very little. One reason I'm looking for this resolution is perhaps it will solve the lack of AA in the sim.
The monitor I’m considering is the Asus PB278Q, compared to Samsung and Dell it’s got the best price and a higher refresh rate.

These are my system specs:
850 Watt Corsair Power Supply – Nvidia SLI Certified
Asus P8Z77-V Intel Z77 based chipset, ATX Motherboard
Intel Core i7-3770K IvyBridge processor, quad 3.50GHz cores, Hyperclocked to 4.7GHz
Asetek Liquid Cooling System
8GB DDR3-1600MHz Quad Channel Memory
2048mb eVGA NVIDIA GTX670 GDDR5 video card
120gb Intel 520 Series MLC Solid State Drive
1TB 7200rpm SATA 300 w/NCQ
Windows 7 Home Premium 64-bit w/ SP1

Surely you mean 2560x1440? Otherwise, that's a very weirdly proportioned monitor.

Upscaling will usually look terrible (at least, it does for me), so stretching 1920x1080 to fit 2560x1440 will most likely look bad.

However, you can use the Nvidia control panel (from what I've read) or possibly the monitor (which is what I do) to perform no scaling on images. This means that if you set your game resolution to 1920x1080, it will display a 1920x1080 image at the centre of the screen. I've use this a few times now and it seems to me that the quality is the same as if you were just using a smaller monitor (one that's right for the resolution you chose).

Though, if you're getting this monitor solely for gaming at 1920x1080, don't bother - it will either look ugly or it will look the same as your current monitor (depending on if you stretch it or don't scale it).

I run IL-2: CoD at mostly high settings and 1920x1080 resolution with a 560 and an i5 2500k, so it's possible that you could run it at 2560x1440, but I guess it's very dependent on what kind of FPS you're aiming for. 2560x1440 has roughly 1.7778 times as many pixel being displayed as 1920x1080, so that certainly isn't a small increase...I don't know, really, hopefully someone else can help you with the graphics card side of things.

Also, I would imagine that at 2560x1440 you would still have aliasing to worry about. Why not try downsampling with what you've got right now? That is, set the game to run at 2560x1440 on your 1920x1080 monitor (you'll have to look up how to get downsampling to work, though, because this doesn't work by default). It won't show you exactly how much AA you'll get from a larger resolution (it might look like less aliasing/more AA than if you were using the appropriate size of monitor), but if it still looks very aliased you'll know that a monitor upgrade won't help much.

Here's one link of many for downsampling: http://forums.guru3d.com/showthread.php?t=346325

I tried down sampling, but it's a complete frame rate killer. Since I don't think CoD handles SLI I don't know how you could send out a higher than 1080p signal from a single card.

I'm running now a Dell U2713H @2560x1440. The monitor I have is not great for gaming as it has pretty slow refresh rate, but is awesome for other stuff.
Gaming at this resolution will require a powerful graphics card with a lot of Video Memory!

I have a GTX590 and is not good enough for that resolution. I have 3GB of video ram, but since the graphics card is dual GPU unit, it divides the memory into two 1.5GB, one dedicated to each GPU. The game will not see 3GB, only 1.5GB so this is a problem with my setup.
If you want to play at that resolution, get a faster monitor, the asus you mentioned above has very good reviews and I'm sure will be awesome. The video card may be a problem, but I'm sure in CLOD, runs faster than mine.

evga makes a 4gb version of the GTX 680, I wonder if that would do the job?

Can you do SLI with two differnt cards? like a 670 and 680 together?

From the review results I've seen, most single GPU cards/single card setups, except maybe the new Titan, are lacking performance at that resolution. The results in most games are going to be below 60fps. I just looked at one test review and the 4GB 680 was around 5fps better than the 2GB version, so I'm not even sure how great that would work.
For that resolution the SLI/Xfire setups and dual GPU cards are king, now that is very dependent of how well the game is optimized for SLI/Xfire.
I think for now, unless you are prepared to throw a lot of money at the computer, sticking to a lower resolution is way easier, specially for a poorly optimized game like CLOD.

No idea.
