It's not as if the hardware isn't capable of doing awesome stuff (case in point: the idTech 5 demo from John Carmack [1]) - the software using it also has to be well engineered.
Good engineering for managing hardware resources at the browser level is still lacking (at this moment, Chrome's various processes are eating up ~700MB of memory on my system - disgraceful!) - and that's what bites Facebook the most.
