HTML5 and Flash won't work any differently with or without a video driver on linux. In linux, a good cpu & gpu, 2Gb+ ram, usually dictates video performance results. Your overall system spec is low, so I wouldn't expect outstanding results. There are ofc ways around this, Minitube for example may be better for Youtube content watching.

Getting custom resolutions on legacy gpu's is not simple in some cases.
