Asus ROG Swift PG278Q vs. Acer XB280HK - exclusively for 3D Vision - Which one?
3 / 4
Well I called Acer support located in India, they were no help and hard to understand. They said that there was nothing they could do, they just handle software support.
I called Amazon, the person escalated it to the appropriate people.
Newegg is having a "Snow Day' due to a Blizzard in the eastern USA that has everything closed.

Sounds like you're having a bit of a nightmare there mate... hopefully get some form or response from Amazon soon then. Just perusing the Acer offerings here in the UK, it looks like they're top spec 3D machine is the Predator XB270HU. It's a 3D/G-Sync/1440p/144Hz IPS monitor (rather than the usual TN panels associated with 3D). Only available for pre-order here so no reviews I can fall to but sounds good on paper. Response time is 4ms rather than the 1ms on the ROG Swift but the improved colours and hopefully getting SLI and 3D to work at the same time could be very interesting.

Philips is also offering a 27" 1080P 3D Vision monitor with G-Sync in the U.S., the 272G5DYEB.
Kind of interesting because they've never offered any of their 3D HDTVs or monitors here before, just 2D.
Judging from everything I read so far 24 inch would possibly be the way to go. It seems to be common sense that 24 inch is the perfect size for 1080p and a lot of people even say that 27 inch is just too big for 1080p so the resolution (ppi-rate) really suffers.
Since resolution is one of the main factors that brought me back to 3DV Surround 24 inch should be the perfect choice I think. This way I am not sacrificing nearly as much resolution (ppi) as with the 27 inch setup @1080p compared to 1440p single monitor and at the same time I maintain the immersion factor through 3DV Surround.
Also a lot of users even claim that 24 inch even adds to the immersion factor because due to the higher ppi-value you are normally sitting closer to the screens and still have both side monitors in your peripheral vision while with 27 inch monitors you dont get much from the side monitors sitting really close unless you constantly turn your head left and right to get whats going on on these screens. Since 3DV Surround means that you are strictly playing on the center screen constant head-turning would make no sense. Well you could sit furhter away but then again the size-Plus of the 27 inch screens would be nullified.
As far as a specific monitor is concerned yes I know the Asus VG248QE seems to be a true classic but right now I am tending to the totally new Acer XB240HB monitor (also Predator-family just like the others that were mentioned here). This one came out at the end of last year got really good user reviews, seems to have thinner bezels than the Asus VG248QE and also is fully 3D Vision certified.

I got a little late to the party lol...
Yes Surround is a beast both quality wise and performance wise. It requires immense power to run 3 screen in 3D (think about it the GPUs need to basically render in pixel the equivalent of 6 x 2D screens !)
I am using 2x780Tis in my surround config (5040x1050 = 3x1680x1050 resolution) and for example let's take Dragon Age Inquisition:
3D Surround:
- In 3D Surround I cannot put everything on ULTRA (Most of the things are on ultra, a couple on high and the vegetation on MEDIUM).
- I can cap the 3GB Vram very easily.
- Frame rate (in 3D) is from 28fps (lowest) to 60fps (highest) avg around 42fps.
3D Vision Single monitor:
- Everything on Ultra.
- Frame rate (in 3D) is from 52fps (lowest) to 60fps (highest) avg around 58 fps.
3D Vision Single monitor SINGLE card (no SLI):
- Everything on Ultra.
- Frame rate (in 3D) is from 40fps (lowest) to 60fps (highest) avg around 50 fps.
So based on the above you can see the performance impact. (Hell I just tested my GTX590 with DSR x2 on one screen and I can reach 50-60fps with that card as long as I don't overflow the 1.5GB Vram)
Also for 3D Surround expect to have PROPER COOLING (water cooling) as your GPUS will run constantly 99% and CPU (based on engine).
Why I still stick with 3D Surround ? It's the pinacle of (3D) gaming in my opinion and nothing beats it... :) I don't mind loosing a few FPS for the extra view which is Immersive and awesome!
I just wanted to "de-mysticize" the 3D Surround in the current day.

You may be late to the Party helifax but you more than make up for it with your shared knowlege ;-)
I am just about to order 3 of those Acer XB240HB mentioned above as well as a single GTX-980 as a replacement for my GTX-690.
The only thing that is holding me back now is your recommendation of water-cooling which I currently don't have implemented in my machine. But do I really need it? Normally my gaming sessions don't exceed 2 - 3 hours.
I bought the GTX-690 powered PC 2,5 years ago as a completely set up system and back then I guess the 690 was definitely sold with something like 3DV Surround in mind. So do you really think it would be inevitable to go for water-cooling now (having in mind that I normally play in short bursts as mentioned above?)

The only reason you'd need water cooling is if you are overclocking your card. The 690 has pretty good cooling already and the 980 definitely has lower thermal requirements. Unless your case has an airflow problem, the card will never overheat, even if you run it 24 hours a day.
You could try gaming on the 3 screens with your 690 first, before buying a 980.
If you look at this graph, you can see that a 690 is roughly equivalent to a 980 in performance.

The only real difference there is the 4G of RAM on the 980, and depending upon games you want to play that could be a factor. I'd suggest that waiting for 6G cards would not be a bad plan, since your 690 still has some legs.

Well I always recommend watercooling for the following reasons:
- Not necessarily Overclocking but there it makes the most sense.
- I like keeping the GPUS as cool as possible when they hit the 99% load especially for long periods.
- Stock coolers on 2x780Ti after 1 hour I got the temperature to 85 degrees.
- Watercolled -> max temperature ever was 63 degrees.
And I have a full tower case with extra fans... so internal cooling is not a problem.:)

My point of view:
- if no SLI = water cooling is not required. Buy a card that has a good AC (preferably 3 big fans + tons of metal)
- if SLI, then it's a different story, but if you can install them with a bigger gap between, and have a decent air-flow in your case, then it's still not required.
After all - you've got 3 years of warranty if anything bad happens. Why would you pay additional money for a mistake made by a card designer/manufacturer?
But that's only my point of view, of course.

@D-Man Why should the ports be a problem? All I have to do is connecting the monitors via Display Port/DVI-cable (Adapter), right!?
@Helifax yeah, being stuck on the 2G was the reason why I was planning to switch the cards. I knew that otherwise the 980 is not really woth the upgrade....just those 2G.
But I think you are right. I will first try with my GTX-690 and then - if necessary - upgrade. If not I will wait with the upgrade until the 6G Cards are coming in!

Careful as to go from dual-link DVI to display port you might need a powered adaptor which is expensive.
That aside, I agree with what bo3b wrote. Bear in mind as well, that SLI scaling is at it's best at high res, so a 690 is still a decent card and that's what I was using for surround/3d surround.
All things being equal, you want as much VRAM as possible, but it's a not a performance indicator as such. The framebuffer uses VRAM, so higher res gaming needs more VRAM, but the biggest impact is high res textures and MSAA. You can work around the 2G limit on a 690 by disabling Aero (on Windows 7) and using FXAA.
All that said, I went from a 690 to SLI 970's and it was a very worthwhile upgrade, especially if you're already spending that much cash on monitors.

Yep, rustyk nailed it.
You would need an active adapter. Club3D offers some, make sure it has Dual Link support and enough bandwidth.
EDIT: lol, don't know why I was thinking of the DP to Dual link adapters.
AFAIK there aren't any DVI to Display Port adapters

You can work around the 2G limit on a 690 by disabling Aero (on Windows 7) and using FXAA.
All that said, I went from a 690 to SLI 970's and it was a very worthwhile upgrade, especially if you're already spending that much cash on monitors.

Yep, rustyk nailed it.
You would need an active adapter. Club3D offers some, make sure it has Dual Link support and enough bandwidth.
EDIT: lol, don't know why I was thinking of the DP to Dual link adapters.
AFAIK there aren't any DVI to Display Port adapters
