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.

Ok well does that mean that my system is still using the 8gb of RAM when it needs it.

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.
