i used to have an XFX 6600GT 256 Mb, and run that with all options in LFS on full, a DDS folder the size of a clean copy of LFS, and a little AA/AF (i *think* 2xAA, 16xAF), and got perfectly decent frame rates - putting this in context, SamH has a 6600GT with 128 Mb and he has trouble with Hi-Res skins, and cant add too many textures without his FPS dropping
