I need to build a new desktop Ubuntu 14.04, for low-end kind of usage. Do I really need to add an Nvidia graphics card for it? I came across some threads e.g. this one, implying things work quite well without it. Some mentions went as far as saying that heat dissipation or power utilization would actually be better without it.
What exactly would be the user experience relying on the built-in Intel card rather than Nvidia? gaming capabilities are not required, browsing vanilla internet sites is. Using a graphical desktop also is required.
