Well on a pc (win) only approx. 3.5 gb is usable through the 32 bit operating system. This memory limit is shared with the video card also so.

No it does not. A 32-bit operating system can only address 4GB of RAM, and that same address pool is shared for all memory addressing. In plain English, a 32-bit windows can only support 4GB and part of that is unusable.
