i dont really have any huge troubles, it crashes every once in awhile (every 5 or 6 hours or so, but usually in specific areas, i suspect my mods)
there are a dozen mods or so for helping with this issue, i use the comunity patches for one.
i have about 8 gb's of mods installed, ranging from teture patches to completel gameplay overhauls.
using the 3gb+ patch will allow fallout to use more than 2gb rams, this to me made a huge difference as well,
anyway if you think fallout and fnv are buggy you should see rage, they have tried cramming so many textures in there as "virtual textues" (virtual fullscreen overlays, basiclally all textures in the gae is made like this)
that you constantly see texture errors when turning the camera, so anoying
