5 is the highest I can go. It won't go above that. The normal map is 2048. Memory allocation is thus: Wed Aug 02 00:21:20 2006 startingimport Wed Aug 02 00:21:20 2006 Trying to allocate 35.193 Mb in virtual memory for highpoly vertices/normals/UVs... Wed Aug 02 00:21:20 2006 Trying to allocate 245.761 Mb in physical memory…
I would temper that with anything at the 21" level and higher is fine. I have a 24" at home but my wife has my old 21" and it's perfectly usable as well. 12-13 might be a LITTLE tiny, depending on what you're doing...
