for future reference, the manufacturer of the card is not as important
as the the chipset. generally speaking there are only two names in
town for advanced graphics, ATI and NVIDIA. in this case you have an
NVIDIA GeForce GTX 480

no

according to specifications that card has "Two pipelines for dual
independent display"

http://www.geforce.com/Active/en_US/en_US/pdf/GTX-480-470-Web-Datasheet.pdf

only the latest generation of nvidia cards(excluding NVS range) has
more than two pipelines.
