Can anyone inform me if nVidias Surround requires the three monitors to run the same resolution or if I can keep my 20"+30"+20"? I'm hoping for the latter...

Let's also mention that the special adapter that ATI requires is $100 so add that to any eyefinity setup you want to do.
To be honest I was expecting a bigger difference between the GTX480 SLI and 5870 CF, given a single 480 is more powerful to begin with and people say how much more awesome nVidia muli-GPU scaling is, I was expecting a pretty big difference. Not sure what sort of deals you guys can get where you are, but out here a 480 is around 28% more expensive than a 5870.
It is disturbingly obvious in our testing that GeForce GTX 480 SLI is superior to Radeon HD 5870 Eyefinity6 2GB and Radeon HD 5870 1GB CrossFireX configurations in 3x1 multi-display gaming. GeForce GTX 480 SLI is a powerhouse of performance at high resolution multi-display gaming. In every game we played it didn’t just come out on top a little, it completely owned the two HD 5870 CrossFireX setups.
Any tri-sli GTX480 benchmarks?
From other posters it would seem that tri-sli 2d surround sees *zero* gains over dual-sli.
That's already been covered in the thread. Though the adapter doesn't necessarily need to cost that much. I've got one that was $10.00. Unfortunately its only passive and doesn't work with resolutions over 1920x1080. If you shop around you can get the active DVI-DP adapters for considerably less than $100.00.
Not true. Here's the thing. What I have noticed is that there is a 142FPS maximum frame rate cap in 2D Surround with 2 and 3 cards so if your game is running hitting that maximum frame rate, which even two cards can do in a lot of games the third doesn't boost average frame rates. Now if your game is running below that rate then the 3rd card seems to scale well. Let me play a little AvP and I'll demostrate. Be right back.
Sounds more like a CPU bottle neck than a frame cap. Those are pretty insane numbers in either case.

If it's always 142 FPS regardless of the game, then more likely it is a bandwidth bottleneck between the cards. PCI-E and the SLI bridge only have so much bandwidth, after all![]()

"If it's always 142 FPS regardless of the game, then more likely it is a bandwidth bottleneck between the cards. PCI-E and the SLI bridge only have so much bandwidth, after all "
I started mentioning this the first day the surround drivers were released. I am pretty sure there is a bandwidth limitation, thankfully it is rather high. I noticed it would hit a wall anywhere from 110 to 140 or so fps. I think it fluctuates in line with how much information the card needs to pull in, thus eating up that cross card bandwidth, and only leaving so much for rendered frames.
But as I said I see scaling in 3D at least in Batman AA at 100% so a hardware limitation doesn't make sense if even one game especially in 3D since that's FAR more demanding than 2D.
I was wondering about that too, and figured it was rendering extra frames but unable to find bandwidth to pass them.
I know for a fact on COD4 when the gpus are maxed I should be getting higher FPS. There is a bottleneck somewhere.
If it's 142 in any game, then it sounds like a bandwidth issue. Not really an important one because even if you've running 120hz monitor you're still beyond the refresh rates.
Fascinating article.
To Kyle & the team: Perhaps rather than CF having poor scaling, is the case rather that the 5870s have serious issues with AA at triple monitor resolutions?
Taking a look at the Crysis Warhead and Metro 2033 apples-to-apples results, the numbers seem to reflect the delta between single card 5870/GTX 480 performance.
Games where having AA enabled is NOT a no-go from the start, i.e. all other titles tested, seem to show ok/decent performance without AA and a humungous crash in fps or input lag/lagging with AA turned on. In your opinion is there a limit with the software? or are the cards just not up to AA, with details up at very high resolutions? Did you get any insights from ATI as a result of this article? I ask because quite often they seem keen to give feedback to you, which you find out from trawling the comment threads.
I'd love to see a company build a monitor with 2 24" 1080p monitors as one single panel. It would be almost like eyefinity, and give you that extra bit of peripheral vision you want, all while being able to be run off any graphics card and use the regular sli/crossfire profiles, which would mean great scaling.
I did think when reading through this "sideport, put your boots on mate!" but instead I would think that theres issues compositing very large frames in the displaying card, or by dint of the hardware design there's alot of data syncing between the two which the nVidia cards do not do/still do but handle it better.
You had the hardware on test, what do you think about it.
( huge props for the site btw, been visitng more or less everyday since the 3870 review)
I don't agree with the magic assumption that everything is about "drivers." It has nothing to do with drivers. If that were the issue, it would have been fixed in the last 8 freaking months or however long it's been broken.

You're joking right? I mean as HUGE a fan Kyle is of Eyefinity, or maybe was might be more correct now, for him to say Surround "completely owned" CF Eyefinity, what else do you want, cake?
EVERY site that's done this review has come up with CF EF getting its ass literally handed to it. It's the biggest blowout in between two first gen products (400s and 5000s are first gen DX 11) parts in years.
Try controlling the hot steam coming from your arse, the only "blow-out" there is the Aliens vs. Predator, the ati solution dropped 100% when enabling 2x AA, which I believe it is more about bugs than anything, all other "apples to apples" are within the margin like how the single cards perform, which is about 20%.
If this article shows anyting new, it shows how unreliable the "min fps" is, just look at the bottom of the Dirt 2 page, a dip to low fps in 2 seconds does not affect the overall smoothness of the gameplay.
GeForce GTX 480 SLI is a powerhouse of performance at high resolution multi-display gaming. In every game we played it didnt just come out on top a little, it completely owned the two HD 5870 CrossFireX setups.
How "big" is big to you? Did you just glance at the numbers, or did you look at the higher settings that were applied on the GTX 480, too?
Don't know where "out here" is but there are some deals on GTX 480s available these days.
Obviously the 480s are faster, a single 480 is faster too, with how much people praise nVidia SLI scaling I was expecting it to better than simply being able to enable a small amount of AA and HBAO.
AA is also something that makes a big difference in IQ, especially comparing no AA to any level of AA. And while HBAO isn't my favorite visual feature, it's definitely a resource hog, so it's nothing small if one card can run it well where another card can't.

The problem isn't AA. The problem is that CF/EF drivers are hit and miss. They obviously use a vastly different crossfire profile to handle passing the information between gpu's, and they simply haven't finished the drivers.
I waited and waited on them to do that... I waited and watched as driver after driver was released with only minimal work done on EF/CF...

Are you kidding?
Metro 2033, nearly the same fps with the 480's on HIGH global and the 5870's on NORMAL. If you've played this game you know that's quite a difference.
BFBC2, 480's with HBAO ON are faster than 5870's with it OFF, and you can deny the importance of minimum frames all you want, but look at the chart for this game and the 5870's drop much lower for much more of the test.
AvP, destroyed all the way around...nuff said.
Splinter Cell. 480's faster with 4xAA than 5870's with none. That's a beatdown however you look at it. And this quote doesn't help, "It just simply felt smoother and better with GTX 480 SLI, and even with just 2X AA it was too jittery and sluggish with Eyefinity6 CrossFireX. "
Dirt 2. 480's running faster once again with 8xMSAA and TR MSAA versus just 2x AD MSAA...another beatdown.
Crysis Warhead, not even close. Much higher graphical settings on the 480 and it still pounds the 5870 setup.
Apples to apples means jack when one of the setups still has enough juice to increase settings, add AA, etc. Using those as your argument is a Pyrrhic victory at best. Run the 5870 setups at the same settings at the 480's, which would also be apples to apples, and it would be an even bigger blowout.
You must not be very familiar with ATI and their hit and miss driver history, which I had the unfortunate opportunity to go thru myself in the 9700 Pro days with about 7 months worth of issues beginning at the time that card was released (August 2002) before it seemed to stabilize (by which point I was fed up anyway), and since 2006 or so thru today with radeon onboard video since this is what all the PCs contain at work.
I've got to be careful about which drivers I use on the PCs I support, I almost never use the monthly catalyst releases since for one, they are rarely WHQL, and two, they tend to lack stability. Mind you not every month. There might be 3 to 6 months in a row where they work fine, followed by 3 to 6 months of unstable crap. This isn't even when gaming either, this is desktop users working in access, excel, and web apps. Don't even get me started on Catalyst Control Center... I can load up 20 new identical PCs with identical software images, and there will be a couple that for no apparent reason have constant "Catalyst Control Center has encountered a problem and needs to be closed.." when booted. I just uninstall it. Usually I don't install it at all but after 6 months I keep giving it another try, hoping the issues will be fixed, only to see the same damn things happen yet again.
