Please forgive me if anyone thinks I have placed the thread. I really didn't know where to put it so if any moderators feel the need to change then please do.

I am about 1 week away from starting a AMD Black build (Best of AMD at this current time). I have everything picked out apart from the monitor.

I went to my local Sony shop and I was blown away with the 3D laptop they showed me. I can honestly say I never thought it would be that good. MY question follows:

In my build I have CrossFire 6990's and I would love to give 3D a go. The monitor I am currently looking at is: http://www.samsung.com/uk/consumer/pc-peripherals/monit...

Just a question - would the 6990's be able to play in 3D and also I have done some research on HD3D (AMD's version of 3D) and how would I get that working on the monitor as I have seen reviews saying the 2D - 3D converter on this monitor sucks ass.

Any help would be taken into consideration as I have my trusty notepad taking notes - thanks everyone.

I recently ventured into 3D myself. I had an unlocked 6950 crossfire setup (similar to a 6990). I was able to use 3D because I did make sure the monitor supported HDMI 1.4a, which will support 3D gaming at 720p. Because AMD's 3D system, actually it's a 3rd party system, uses HDMI instead of dual link DVI, it cannot run games at 1080p in 3D. I used TriDef 3D drivers and was able to run games. It took a bit of work to learn all the settings and get things running, but it looked pretty darn cool in 3D.

I then decided to see what it would look like with Nvidia's 3D vision. I moved over some 470's in another machine and installed them in this one. I then played the same games I tried on the AMD setup, and everything looked a little clearer. The textures were crisp and it looked pretty good. Then I learned how to adjust the settings, and the Nvidia 3D vision really came alive and blow the AMD setup out of the water.

I HIGHLY recommend that you reconsider the 6990 and get an Nvidia setup. Perhaps a 590 if you are sold on a single card setup, but I'd recommend 560 ti's or 570's if I were to do it all over.

One more thing you need to be aware of. AMD's HD3D does not work with crossfire. That also means it will only use one half of each of your cards. Nvidia's does use SLI in 3D vision.

AMD 3D is garbage.

They support like 3 monitors:

I'd recommend GTX 480s or 580s for more VRAM because nvidia doesn't really offer a 2GB solution (I haven't see any benchmarks on the 560 Ti 2GB and can't recommend it).


It supports more than 3 monitors, and the one he is looking at does work. It's just AMD is not pushing 3D so they have let their list sit there without an update. I do agree that you need to look at Nvidia for 3D, if you want good results.

I just want to thank you all for your input. I guess Im just going to go with a normal HD TV then :(

You can still go for a 120hz monitor. 120hz is very nice to have, even when not using 3D. It does work with AMD, but not very well, at least, not nearly as well as it does for Nvidia. I take it you already have the 6990?

For AMD, they do very well with 3 lower end monitors in eyefinity. Perhaps that something you'd like to look into...assuming that you are looking at new tech.

Yeah I am still going for the 120HZ but there is one without 3D for $300 and it basically has all the same specs but no 3D. I just want to ask you what you mean by ''it does work with AMD, but not very well''. Are you talking about the 120HZ or 3D?

Thansk for the help by the way, I learn something new every minuet on this website.

I was referring to 3D. If you use AMD's version, you are limited to 720p rather than 1080p. It also does not seem to work outside of Dx9 (although most games are dx9). The software is 3rd party, which you will need to buy for the full version. The 3rd party software is also more difficult to use.

Nevermind then, I am just getting back into PC gaming - my last game on PC was 'The Matrix Reloaded' - like 6 years ago hahaha. I missed it so Im getting a 89% beast rig - I guess only the i7's and better right? anyway thanks for yoru help and I have decided to gow ith the exact same version without the 3D. Can't wait to see how crisp it looks.

I have a HD 5870 (single card no crossfire) with a HDMI 1.4a 120hz 3D monitor and I can game in 3D at 1080p just fine. AMD HD3D does support 1080p BUT unlike Dual link DVI 1080p only works at 24 hz instead of 60hz. This is not a limitiation on AMD's side but a limitation of bandwidth in HDMI 1.4. It cannot push enough data to do 1080p at 60hz.

Just so this is clearer, when you talk about HDMI 1.4a (you keep leaving out the a, without the a, it doesn't work with AMD at all in 3D), when they say 1080p 24hz, it's 24 per eye, so it's like 48hz. It can run 60hz at 1080p as a normal monitor, but not as 3D. 720p 60hz 3D is the same as Nvidia 3D vision at 720p @ 120hz. I don't know why they list it differently, but they do.

As a result, the AMD setup cannot run it as a regular monitor at 120hz with HDMI, but it will run 120hz as a normal monitor with a dual link DVI cord, but you can't run HD3D with DVI on AMD. This is annoying if you want to go from 120hz gaming to 3D gaming, as you'd have to change the connection each time you change.

For movies, 1080p @ 24hz is good, but it sure feels like hell in a game.
