If i had my gpu and it had for example 2gb vram. If i played a game and it exceeded the 2gb vram limit and it would be using RAM as the memory next. If i had lets say ddr3 1333mhz memory vs ddr4 3200mhz ram would the ddr4 act more as gddr5 memory because its almost as fast right? Or would the ddr3 1333mhz ram act the same or slower and laggier and make a difference.
