Is it possible to run 3 monitors on two different video cards. I currently have a Asus gtx560 and an old 9500gt 1gb, Three 19inch 1280x1024 LG L1953T monitors. I want to know If I can use the 9500gt to run the third monitor. Also would doing that slow my computer down (My motherboard is an asus P8H77M). If the second nvidia graphics card solution isn't possible, then is it possible to use the on board intel graphics to output the third monitor through the motherboard

other setup information
OS-windows8.1
CPU- i5 3570
Ram- 32gb (for video editing)
Motherboard - asus P8H77M


Additional question. Assuming it is somehow possible to run all three monitors without performance loss or errors using 2 entirely different video cards, Would it then also be possible to run games across all three monitors using the performance of the gtx560 (like Grid, BF3, starcraft 2).

Its perfectly possible to run a second card for an additional monitor.

You can run extended desktop just fine on it, naturally you cant game across all 3 screens.

If you had lower end hardware I would worry about it handling it, but with an ivy bridge i5 you have nothing to worry about.


There is a feature they started doing in socket 1155 boards (2xxxx and 3xxx series i3/i5/i7) where you can use integrated graphics and dedicated graphics, would have to lookup if your board supports it.

As long as you have the necessary additional PCIe slot and a PSU capable of supporting both cards, then it should not be a problem. For those two cards it would be recommended to have a very good 750w or higher unit. No low end, OEM or budget power supplies that are likely to not meet their rated capacities.

For gaming the 9500 might come in just above his HD4000 on his ivy bridge CPU.
For not gaming there should be no noticeable difference. When you figure in the extra power and cooling over using what is already there, makes the HD4000 the clear choice for non-gaming.

I have a corsiar 650watt so power should be fine. what about driver support. will I need to run 2 differnt set of drivers. newest drivers for 9500gt is 341.44 released 2015.2.24, do I need to run 2 different sets of drivers, or just the most recent gtx560 ones. while for my gtx 560 353.30 realesed 2015.6.22. will it work like that? Silly question perhaps but using extra PCI-e lanes on my motherboard will not slow down my gtx560....right?
