Alright so I'm getting a new desk and I have enough room on it to put my 26" HDTV on it with my two 23.6" monitors to the side. I am running 2 EVGA GTX 275's in SLI mode right now with the two 23.6 inch monitors. Can I use one of my DVI ports on my second GTX 275 to display on the third screen? Any help would be appreciated and here's the link to the new desk I'm getting.

Sorry for double posting but I looked more around the internet for 3 way display with 2 way sli and it seems not possible unless you get a third card or disable SLI mode. Well I was thinking would this work

I would have my two smaller displays plugged into that and I would have my main display plugged into the other DVI port on my video card. Is there anything wrong with this setup that anyone can find or have I found the solution? lol

I would just disable SLI when you need the extra monitors.

That switcher will duplicate the same signal to the other monitor, it will not allow you to use it on its own. That will require a 3rd card for that purpose or you to disable SLI when you want it.

Alright so lets say I get a EVGA 9800GT as a 3rd card, can I have that card run PhysX and also display the third monitor? I have 1 extra PCI-E x16 slot or x8 doesn't matter really.

Alright I went on the SLI faq zone and found out that it has to be PhysX capable. Alright so my last question and sorry for this everyone, should I have the two smaller monitors that aren't my primary monitors being displayed from my 3rd GPU that isn't in SLI mode while running PhysX? Will displaying 2 signals decrease the PhysX performance or no? Thank you for your help
