120hz for triple monitor setup

Not really no...

Considering you'll struggle to find graphics cards able to get you over 60 FPS at 5760x1080, it's pretty pointless.

Just get IPS screens
 
Yeh, I agree with the above. You would need something like a 690 sli config to be able to game smoothly at 5760 x 1080.

You'd end up getting negative results adding more cards to that.

The best cards you could run would be like 7970Ghz in 2 way crossfire, and even then you'll probably only just break 60 FPS at that resolution.
 
690 sli @ 5760x1080 is a fail, not enough vram for 4 gpus grunt at this res

'cheap' option: 2 x 680 / 2 x 7970 on z77

otherwise 3 x 4gb 680 / 3 x 7970 on x79

Personally I am buying 2 more 2420ts (120hz) soon. FPS will be fine for now on most games. BF3 I will need to drop msaa to a max of 2x. 4x runs dangerously close to 2gb vram limit but the fps will be unacceptable due to the grunt needed anyway. But tbf I barely play bf3 because it's boring.

To answer OP, depends what you want. You don't need to be @ 120fps to get the benefit of 120hz panels as they are smoother @ 60fps than 60hz panels I've owned. However they are all TN panels with colours and viewing angles much worse than an IPS/PLS etc. Bare in mind if you're looking to go 3d over 3 screens (e.g. 3d vision) then you'll only really be able to do that with some older or less demanding titles..

Yeah, quad sli is detrimental to performance. I was just giving an example of the amount of power needed to run such a setup efficiently.
 
yep going to get 3x 7970 water cooled and overclocked. so what panel should ii get that will have great color and a 2ms response time
 
anything over 2 cards can have negative effects in gaming - ie - you'll get possibly lower frame rates than just using 2 cards, or you'll get an increase of something like 3 FPS...

Why 2ms response time?
It really doesn't matter than much.

Get IPS panels - either LG, iiyama or Dell seem to be the best bets at the moment.

all the reviews i have seen show an increase in frame rates when there is 3x cards i know this is true for 4x cards but this is the first i have herd about three cards dropping frame rates
 
I really wouldn't bother with 3 cards, I would do what James is saying, go 2 way sli or crossfire and get some ips screens. I have the LG IPS223 and I think its great although I have never owned a 1080p monitor before so have nothing to compare to
 

You have to look at the results with reason.

1920x1200 = 2 FPS Difference
But 2560x1600 = 17 FPS Difference

The difference when you add three 1920x1200 screens will probably be about 30 FPS or higher.

Me personally I've had a Tri-SLI (3x480GTX) rig and it didn't work that great for me, Dual SLI worked much smoother but I think those results from Guru3D do show that the greater the resolution you go the bigger difference adding that 3rd card makes.
 
Well if you want to spend all that money on 3 cards at 3 high res 120hz monitors then by all means go for it but I wouldn't recommend it

Sorry - I didn't even read the results fully before posting...

I would however argue and say that that's due to the extra RAM maybe, and not the extra processing power?

Why not run with 2 to start with? You can always add an extra if you feel the need.
 
ok i will o with two cards after i do some more research i will have to see how games like bf3 react to 3 way. A quick question is 5ms that noticeable compared to 2ms. BTW thank to everyone for the help on this
 
careful when using BF3 benchmarks to give people advice. Most bf3 benchmarks are done in single player movie scenes. This was a huge mislead for CPU benchmarks and has a lot of people thinking the i5 and i7 are equal in multiplayer, that is not true at all according to multiplayer benchmarks, with significant improvements going from each i5-i7 quad to 6core intel. I dont know if the GPU benchmarks are hampered the same way or not, maybe it stops reading/using improvements in the movie scenes past a certain point.
