If you have more ram does it help the graphics card?

no graphics cards have there own built in video ram

The above answer is only partially correct. If a computer had onboard graphics, where there is no dedicated graphics card, then the graphics chip is on the motherboard itself. In this case, it will use the system RAM for memory. This can reduce the total amount available to the system.

So if you have onboard graphics (no dedicated graphics card), then a dedicated GPU(graphics processing unit) could in fact increase available RAM. However, the difference is not likely to be large. RAM is cheap. Your best option is to buy more RAM for your system.
