They do not have to be the same resolution, I would like for all the to be working on the same computer. Example- One page excel, another word, last one a video. I don't expect to have one video across all three.
As this is my first post, I am sorry for the lack if information.
You posted more than enough information, dont worry there.
vmem is talking about eyefinity with the same resolutions, dont worry about that.
The thing is though that your nVidia card does not do more than 2 monitors, and your motherboard I dont think supports adding another video card, SLI.
Next, the card you have picked out, an XFX 6670 does not support 3 monitors and thats roughly the best you will be able to do for $50. Any chance to increase your budget a little bit more?
I will look for a cheap card that supports 3 monitors
