Hi,

My rig curently has a GTX480 with two monitors attached. I would like to add a thrid monitor and was wondering if this http://www.newegg.com/Product/Product.aspx?Item=N82E16814162067 GT430 would play nice with my 480. I am not looking to run SLI but am simply looking for a cheap solution to add a third monitor without killing my performance. The third monitor is going to be a small 14 inch lcd.

Thanks,
LouP
 
Thanks guys,

Card ordered. I thought it would work but hoping it doesn't cause any performance issues. I have two PCIe x16 slots in my MB so hoping all is OK.

I have 3 monitors, one connected to my gtx 580 as my main and two connected two my gtx 460 since I only game on one screen.
 
More power to ya! That should work fine! Now if only I could combine my 260GTX and 5770...
 
You will be fine.

I had a gtx 580 and a gtx 260 recently in fact... worked great, even used the 260 for physics.
 
If you have Windows Vista you cannot use different drivers for the video cards, so this would eliminate the possibility using a Nvidia and AMD video card at the same time.
 
OK, so everyone knows, here is what happens on my machine with the second card installed. I got this card to use on third monitor while running FSX. My rig will run FSX at around 30 fps with settings pretty much maxed out. As soon as I undock a window to drag to the third monitor (which is what my intention was) my fps drop to the mid teens. It doesn't matter if I drag this window to the third monitor or not. As soon as I close the undocked window, fps jumps back up into the 30s. I can run programs outside fps on the third monitor and they have no effect on my performance in FSX at all. It's like as soon as I undock a window, FSX "sees" that third card whether you use it or not and slows down. Close the undocked window and it doesn't see it anymore. Bummer, because I got this thrid monitor for the specific reason of monitoring undocked windows while flying but maybe I can find run some program outside FSX to utilize while flying. Freak'n PCs, seems like there is always a catch when you try and do something like this.

interesting error, never heard of that happening before. i run dual displays and move crap around all the time while playing games even when i had my second monitor connected to a different card. you could try messing with the settings in the drivers. a setting i found that helped me with ET:QW(only friggin game that was sensitive to my second monitor) was enable single display performance mode in the 3D applications settings. may work or may not. other then that the only thing i can think would cause a problem is Aero since it doesn't disable sometimes when gaming and having 1 of the displays sitting on the desktop.

correct but just so the other person doesn't get confused, you ARE able to run different drivers(nvidia & ATI/AMD) drivers at the same time in windows 7.
 
Thanks,

I quickly took at the nVidia settings but did not see anything wrong but I do not remember checking to see if the third monitor was running in performance mode. I'll let you all know what happens, so there may be hope yet.
