Can a video card help lack of RAM?

My dad has a 2 ghz processor with 1 gb of ram. He runs a lot of programs and it is over loading his ram. The problem is, his computers max amount of ram is only 1GB his computer does not support more than this. So if he gets a new video card maybe an nvidia 256mb ddr or something along those lines will it add more ram in some sense? Could this help solve the problem or will it not make a difference because he only has 1gb? Again his computer cannot upgrade he is stuck with 1 gb of ram. Will a video card help? He only has a 64 MB video card and the reason I believe it will help is because on my computer I can view how much of my VRAM is being used and even when not using anything too graphic demanding just browsing the net it will jump from 60-120MB or 140MB of VRAM being used... So I figure that little bit of extra video ram (VRAM) could help him because once all of the vram is used it will start using your system ram for video which causes there to be less RAM for other processes slowing down the computer. Is this true?
