AMD processors and Nvidia have been known to give some people a small fit, but your answer is yes, they will work together.
Yes, but the performance on the PCI card will be inferior and you will probably not be able to do anything 3d across both monitors. Both cards must be of the same manufacturer - ATI & ATI or NVidia & NVidia etc.
A user of the application Ubuntu would need to install the Nvidia driver because default driver that comes packaged within the Ubuntu application lacks the ability for 3D graphics acceleration.
NVIDIA drivers are free to download from NVIDIA's website.
Nvidia was created in 1993.
The population of Nvidia is 7,000.
The software coordinating multiple monitors between the GPU and the OS differs between ATI's driver (where its known as HydraVision) and Nvidia's, (called nView) and both sets of code dislike one another vehemently.... If neither your integrated ATI or discrete Nvidia graphics cards has two monitor outputs, you should exchange the Nvidia card for a comparable model with an ATI GPU. If one of your current GPU's has two monitor outputs, disable the other card, and implement the corresponding multi-monitor mode associated with that graphic driver. ☺

nVidia by far. But it depends. If your looking for game play then get your self a nVidia card.

Drivers are files that help your computer understand how to use a part. Nvidia is a brand of Graphic cards. Updating your Nvidia drivers is important. www.Nvidia.com
