Yes and No... If you notice, in 64bit systems this is not an issue. The reason for this is that a 32bit system can only address 4GB of memory. Devices lice Graphics cards need graphics memory (so here you are correct, onboard video will use the RAM for its graphics memory). However, if you have 4GB installed on a 32bit system, it will not show the full 4GB even if you are using an external (after-market) card as the ram on the graphics card needs to be addressed and will cut in to the system ram's address space.

So say you have a system with 4GB RAM and 3 quad-monitor video cards each 512MB RAM. If you are running on a 32bit system, you will only see 2.5GB in the system.

Cheers
