But the video cards have their own RAM; why would they need to steal it from the system?

They have their own RAM, the issue is with something called address space. On a 32-bit system you have 4GB of address space and all devices you need to use have to be mapped into the address space. Each device that gets mapped in will carve out a bit of the address space and render it unusable for the rest of the system.

Ah..! Interesting. Perhaps I should install 64 bit Windows?

yup, it's the only way to use more than 2.5-3GB of memory
