F3 and FNV weren't much more than 4Gb without add-ons. I undesrtand your concern though. From the few leaked videos, we can sometime see some quite ugly textures, especially at places we're not supposed to see from too close, like the ceiling of big caves and houses, some distant rocks in the moutains, the higher end of a fortress' walls, etc... No big deal for all I know.
