the bitmap of the screen must fit into the graphics RAM ?
1024 x 768 x 3 (true color RGB) == 516096 Byte ?

All other RAM is for 3d Graphics to store textures, 
back buffer, alpha buffer and accumulation buffer ...

The OpenGL extension may need some more but the 
native OpenGL interface for real time graphics
used by Mathematica is so simple (no textures,
no alpha blending) that a front and a back 
buffer are sufficient.
So for making a real time 3d graphics that cover
your screen you will probably need 1 MByte video

The 3d graphics of Mathematica is obviously
so slow that there can't be a hardware acceleration.

Using my OpenGL viewer or an other OpenGL addon you may
need sufficient more.
