Triple Screen 120Hz Help!

[Liarma]

Ok guys I need some help here. Basically I want to buy 3x Benq XL2410T 23.6" 120Hz 3D Monitors and running them in Eyefinity at 5760x1080 at 120Hz.

I'm currently running a Sapphire Radeon HD5870 1GB which I know isn't enough for that setup so I'm going to be upgrading my GPU. I was considering the GTX690 but seeing the price that is now out of the question. I'm really liking the Msi 7970 Lightning 3GB. It has enough VRAM for that resolution and it overclocks like a beast.

The only thing is I've heard from some people that AMD cards have problems running eyefinity at 120Hz and you need an assortment of different adaptors to get it to work and even then it's very buggy and doesn't always work.

I've heard that Nvidia cards can do 120Hz Surround out of the box with no adaptors required and works flawlessly. But would rather not as the GTX680 only has 2GB VRAM and is a lot more expensive than the 7970 price/performance wise. And the GTX690 is almost $1700AU.

So can anyone tell me if I were to buy a 7970 Lightning what would I need to do to get it to run Eyefinity 5760x1080 at 120Hz?

Thanks in advance!

If it was me i'd get a 4gb 670, at stock a 670 is pretty much neck to neck with a 7970 and beats it in some games, when overclocked it performs faster than a 680 in most games as well.

 

[Rastalovich]

Any particular reason for the 120Hz ? Other than that, afaik, if the monitor can do it, the card(s) should allow it.

no 4GB GTX670's availible in Australia atm it would seem, and I really love the look of the 7970 Lightning. I have a side window in my case so aesthetics is important to me too. I know it sounds stupid but for me looks is a big thing and the 7970 Lightning is one sexy card imo!

120Hz is a lot smoother, I have used my mates 120Hz monitor and my eyes can see a huge difference. Kind of annoyed because since using his 120Hz monitor I am now completely dissatisfied with my 60Hz

Shame about the 4gb 670s not being available, the Lightning is an overclocking beast anyway so there is plenty performance in it.

I can see the argument. Having a monitor that can do in excess of what your graphic card can do, usually, in terms of pictures per second should be better. I can also see the argument that the eye can't detect it. But I feel the eye can detect multiples of what people claim it can detect. Factors if you like.

Whatever floats your boat imo.

Can anybody shed some light on this please?

unless using 3d for every thing (120hz = 60hx+60hz for 3D) i have a hard time spending

$750+ for 10-15% advantage in "looks".

i cant 3D too long as it tends to tweak my noodle and optic nerve.. so i canned the 3D

until the "references" are improved.

3 monitors, better GPU (water cooling is comming i feel it), and lighter wallet cant be a better

experience, imo. just wanna get you all of the input to make this expensive decision.

I want the triple monitors for a few reasons: multi-tasking, being able to have several windows open at once. surround gaming, it's a novelty but freaking awesome with BF3 and Crysis 2. Also the monitors are on special atm for $250 each which is a steal considering the specs of them. I want to run them in 120Hz 2D Because my eyes notice the difference and games are much more fluid and smooth for me. I just want to know if I can run 120Hz eyefinity out of the box or if not, what adaptors I would need to make it work.

Pretty sure you need a non passive adapter, best bet would be grab 2x 2gb 670, they have no problem running BF3 on ultra on 1080p surround, 2x 670 is only a few FPS slower than 2x680 or a 690 and you save a bunch of money.

*fps taken from another review site*

BF3 Maxed out 5760x1080,

670 = 27

7970 = 30

680 = 30

2x 670 = 52

2x 680 = 54

690 = 55

ok cheers mate, would the 4gb 670's make a difference in fps at that res in BF3?

Probably BF3 loves them ram. Also I prefere more ram in any case. the bigger the ram on the card the less likely you'll run into restrictions later on ^^

From the tests ive seen when i was looking into BIG res multiscreen setups, using 2x, 3x and 4x sli 580 1.5gb vs 3gb setup as the results im pulling from its actually a rather minimal loss going with the regular cards over the twice as big cards and it doesnt cost you an arm and a leg for the minimal fps more.

If i had to guess from what ive seen id probably say the difference between 2x 2gb 670 and 2x 4gb 670 would be somewhere around the same fps gain as going from 2x 2gb 670 to 2x 2gb 680 and both setups would cost around the same, id just stick with 2x 2gb 670's man and put the extra money towards something nice(like buying me my 2nd 580?

)

One thing you really dont want to do tho unless you upgrade to a pci-e 3.0 setup is get a 3rd 670, 2x are fine in a pcie 2 board but 3x and 4x takes a MAJOR performance hit in games that support 3/4way sli well (like cyrsis 2, bf3, skyrim to an extent but its a bit hit and miss still on skyrim sadly)

3d dp to dl-dvi adapter

You need a displayport 1.2 graphics card though, ie: 6-series or later amd card.

or try to find a 590, the 120hz is really awesome when fps is above 100

Is there enough bandwidth on any cards today to run[font="Verdana, sans-serif, FreeSans"] 5760x1080p at 120Hz, and if there is I would assume that there is going to be significant screen sync issues. Has anybody seen this done before. If so what Graphics config was it on.[/font]

I have seen it done on an ASUS DCUII 7970. Not sure what adaptors etc. were being used though.

 

[JackyBoy]

Yeah if you go amd you will NEED an active display port adaptor (to go for anything more than 2 monitors). Found that out the long, hard, frustrating way.

Or have a display port monitor
