"At a minimum, Maya requires a system with:
Windows: Intel® Pentium® III or higher, AMD Athlon™ processor
Macintosh: Power Mac® G4 and G5
512 MB RAM
Hardware-Accelerated OpenGL® graphics card
3-button mouse with mouse driver software
450 MB of hard disk space "
So I think you need to upgrade your PC memory anyway. Heres some stuff on Laptop 3D click here more games oriented, but worth a look.
