so, im building a new comp, and im definitely getting 3 monitors this time, and either 2 or 3 graphics cards.
ideally wouldn't it be better to get 3 (well obviously) but is it like one monitor runs off of one graphics card in the ideal situation?


sorry tongue.gif never really read into sli setups

If going 3x 1080p, ie: 5760x1080 you can run most titles pretty easily with 2 GPU's in SLI (If your going GTX680's) 3 or more is all dependant on your budget. But 3 is quite sexy....and will monster anything you throw at it. But is 3 needed, no.....lol

basically when you have a SLI setup in some games 'that' do support SLI the game would run off both cards giving more performance to gaming.
In some situations where the game does not support SLI, your game would run but in one card performance, one card would be doing the work and the other would be idling. but nowadays most games do support SLI and what ever the count of monitors you have you will still have a boost in performance

so what about this

example: i have 3 monitors and 2 gpu,s. would it be ideal to run (and by run i mean connect) say the center monitor to one gpu, and the left and right monitors to the other gpu? thus resulting in higher fps on the middle one (the one im looking at directly) and less fps on the sides (because they are sharing a gpu?

is that correct?

It doesn't matter how you set it up, so long as all of the monitors are plugged in to the correct ports (DVI to DVI, HDMI to HDMI, etc.). I just randomly plugged two monitors into my top card and the remaining monitor on the bottom card. You can do the reverse and it would still work. wink.gif

Once you go to set up Surround, you can rearrange the order of the monitors however you like so that it flows smoothly from left to right, and vice versa:

Suffice it to say, the drivers are robust enough that you can plug it in however you want and still be able to configure it correctly. thumb.gif As far as it affecting performance, it will not make any difference. The rendering of images are still split amongst all present GPU's. smile.gif

The games will see the 3 screens as one large 5760*1080 screen. So the fps will count for all 3 screens. Also the gpus will work together and will not power the screens as how you think. Its like a dualcore cpu doing one task.
But then its the gpus. You can visualize it as one proccesing unit with 2 cores (gpus) in 2-way sli.
