6870 Crossfire 3240x1920 Performance?

post #1 of 21
Thread Starter 
How will dual 1GB 6870's in Crossfire handle games like BC2 and upcoming shooters in triple 1080p Eyefinity? I've got two Dell U2311H 1080p monitors currently set up in portrait mode and plan on getting a 3rd sometime.

Now I've read on HardOCP that the 1.25GB GTX570 and 1.5GB GTX580 run into serious VRAM limitations at 5760x1200 (3 x 1200p screens) when AA is turned up, whereas the 2GB 6950 and 6970 cards don't have this issue. Right now I have a single 6870 but I'm considering ditching it for a 6950 to unlock into a 6970. If I do that, however, I won't be able to afford a 2nd 6950 for a while.

Another question: does AA really improve image quality much when the resolution is so insanely high? I'm used to gaming at 1080p with only 2xAA and while I can still see the jaggies, it's not terribly bad. I would think that ultra high resolutions wouldn't benefit as much from AA, but the HardOCP editor stated that AA is MORE valuable at high res. What's the deal here?

u are talking about 5760x1080 right? i don't believe that it will go smooth because you will be using 1gb of vram, instead it will be better to go with a 69xx card because of the 2gb vram ...... but is my noob opinion.......................... by the other hand did u see this video?

I'm actually talking about 3240x1920. I don't have enough desk space to put 3 monitors in landscape view. Portrait is my only option right now, and I think it actually looks better.

Yeah I've watched that video multiple times. Looks decent and he's only using a single 6870, however he didn't state what settings he was running the game at. I want to run most of my games at absolute maximum settings, with the exception of AA. I think I can live with 2xAA.

It would be REALLY helpful if anyone who is running a single or dual 6870's with Eyefinity could post some benchmarks or just share their experiences.

EDIT: single/crossfired 5870 benchmarks in Eyefinity will also help

Give me a minute, I'm on my phone, I can look for some benchmarks. But I would think the power of 2 6870's would be able to run pretty much everything on all high.

The have almost perfect scaling.

Edit: Shouldn't the resolution be the same as the other?

As long as the number of pixels is about the same, aspect ratio shouldn't matter, right? And I know the shader power of two 6870's would be enough to run everything smoothly, it's just the 1GB VRAM that worries me.

So performance will actually be better than at 5760x1200 because your resolution is actually smaller(1080p compared to 1200p monitors).

As for the 1GB of VRAM, you should be able to get some AA, but at the higher resolutions, AA is much less noticeable. 2x - 4x AA will honestly probably be all you need, and 1GB of VRAM is plenty to do that at 3240x1920.

Do you think 6870 Crossfire could handle BC2 on max with 4x AA at 3240x1920? My definition of smooth for that game is an average of 55fps with a minimum of 35. I wouldn't mind turning AA down to 2x if it lets me reach that goal, but I need to know for SURE if 6870 Crossfire can pull it off.

I'm not going to say it will for sure at 4x AA (though I'm pretty certain it should, the only trouble you should have is at 8 - 16x AA), but I found this chart showing scaling 6870 CrossFire scaling in an eyefinity setup:



I don't think you'll be hitting the 1GB limitation on the VRAM until 8x AA, and CFX 6870's should be powerful enough to play BC2 at that resolution.

I don't know for sure because I don't have the cards, I'm just showing you what I've been able to gather from reading and what not.

Dang, if it scales that well by adding a 2nd card, that suggests that there isn't a VRAM limit. I think I'll be going Crossfire soon, then.

Well if you can, I would test it on your first card, and see how it performs. That way you kind of know what to expect if (when) you do go crossfire...

Anyway good luck!
