That is correct. The video performance is based upon the videocard processor, not the dedicated ram. However, in more complex games and graphics, the texture is larger and more complex, thus required larger space to temporary stores it while it feed to the processor for processing.
Thus, you see small performance gain if let say benching HL2 in certain resolution and texture setting. However, if you max out the resolution and texture setting, you will see a much larger gain with the larger memory.
