In short does this compute ???

Im looking to buy 3 new 24" Monitors and as I have AMD GPU's ill be useing Eyefinity will I see the benifit from 120Hz or am i better of sticking with 60Hz ?
 
As per the other thread, 120hz gaming is smoother but as people point out IPS panels do have better image quality as all the 120hz panels are TN.

You can even get some 144hz panels.

Try one if you can to see if you notice the difference.
 
Yeah I see that but the question is does the screen run at 120Hz when in Eyefinity mode as there seems to be a question around this ie when in Eyefinity mode they drop to 60Hz ??

So if they are going to drop to 60Hz when in Eyefinity mode I may aswel just buy 60Hz screens.
 
So a bit of digging and the answer was right under my nose in these very forums ....

So the answer is NO ..... as I was informed buy 5UB that this may not be possible he was infact correct .... good call 5UB.

Eyefinity drops them back to 60Hz ..... so unless someone else can correct me then im heading for 60Hz monitors :-)

Just some balancing information - I can personally confirm that nvidia surround over 3 120Hz panels works at 120Hz (even 144Hz).
I think that thread that you quoted was talking about mixing both 60Hz and 120Hz capable panels in a surround configuration, where it always picks the lowest refresh rate of any included monitor for the surround display mode.
If you're buying three 120Hz-capable monitors I'd doubt you'd have a problem running at 120Hz across all three - and as mentioned I've confirmed this is okay for nvidia, but i'd do a little more research to confirm that this is also the case for ATI. Common sense tells me it will be fine though :)
 
Oh I also have a 60Hz 4th monitor connected as an "accessory display" and this doesn't affect my ability to run the surround configuration (with the other 3 monitors) at 144Hz. Remember this is all on an nvidia setup...
 
Played Eyefinity with three 120 Hz monitors. As long as they're all connected into 120 Hz able sockets (e.g. mDP or DL DVI) they'll run at 120 Hz.

But as a side note, running 3 120 Hz monitors into one card means quite high idle temperatures as the card won't clock down as much (or at all) at idle.

With nVidia surround you plug two monitors into card one and then the last monitor into card two (multi-GPU)... with AMD they all go into card one irrespective of how many cards you're running. It's annoying if you aren't water cooling.
 
Also, driving 120fps on 3 monitors would need a lot of power, im thinking more then what you have for modern games at highest settings (forget AA).
 
Good point, completely forgot about that. But to drive at 60+ will still need a lot of power. Hitting 70 really isnt worth it IMO

Depends on the game. Without MSAA/SSAA a pair of 7970s will push very good frame rates. If you can handle FXAA you're sorted :).
