So I have an APU (AMD A8-5600k quad core) and I recently increased VRAM by using the 4gb of RAM I haven't noticed any boost in games so in result would I have to increase my ram to make up for its loss?
VRAM(video ram) and RAM(computer ram) are two different things. Video ram come directly from the graphics card itself while RAM is basically the whole computer. Unless you are using integrated graphics, I believe that it does not effect the video ram.
