This should really be in the 3D forum...
Depends on your definition of "low-spec". I'm using a P3 550 w/GeForce 3 for most of my basic work, and havent (yet) hit an unacceptable amount. It all depends how you're loading things in and what the poly count is. If you try to restict the game from only loading what it needs for a particular level you shouldnt have too many problems.
The only limit is what your target system can handle - run a few tests to be sure.
FYI: My (now ancient) World Editor loaded in no less than 500 512x512 textures without problems while dealing with open areas of 10,000 polys or so.
