Get 2 580's, you don't need 3 cards, scaling of the 3rd card is horrible in 3D Surround.I have about the same setup, i dedicate 1 GTX480 to Physx for 3D surround, i found that i have less driver related issues using 2 cards.

I have played a ton with both gtx480 sli and tri sli. There is only a small difference between them. TBH, the limiting factor is frame buffer (VRam) and texture units.

I would get 2x gtx580s. DO NOT GET 570s or 470s, at that res you need all the TMUs and memory bandwidth you can get. The normal rules of scaling don't apply the same way.


So yea.... get 2x gtx580 and be happy.

OK thanks for your suggestion biggrin.gif
May I ask how many FPS increase do you get from one card to SLI to 3-Way SLI in your configuration? It's hard to find a GTX 580 review that using multi-monitor display.

Is it true that Nvidia cards won't go to 2D mode when idle if using more than 1 display? So the card won't go to power saving mode and always use the max power even if it's idle.

I'm using a similar setup and have to say I don't really like 3D surround. This is mainly because of the glasses. You end up seeing the side monitors in your perihperal vision outside of the glasses and it screws it up. I much prefer just using 2D surround for gaming and 3D on a single monitor.

You can see my surround videos on my Youtube channel.

3D needs rendering power => more cores => 580 in general.
3 monitors take more v-ram so again 580's 1.5g is better.
So i say 580s all the way. Sli, 3-way, watercooled, oc...etc

They are all pretty much based off the reference design at the moment. I overclocked my 580's and didn't notice that much more in performance either btw.
