I am reading and watching as much as I can to get ready to assemble my i3v 12" once it arrives

Im confused about the RAMBO setup.
when I watch the video (http://www.youtube.com/watch?v=sOojWpuci_o)
on ramps firmware

It suggests that once i run the arduino software I open up the appropriate files

my options based on the download link from makerfarm are:

Marlin_RAMPS_EPCOS_i3_6inch
Marlin_RAMPS_EPCOS_i38
Marlin-Graphical LCD

which one do i use?

or do i use the separate download link for Rambo firmware?
