Graphics Card Not Avalible in Blender Internal For some reason Blender does not use my GPU when rendering, even though I have my card selected in the user preferences 

When I render, my CPU usage goes up to 100% and MSI Afterburner shows no increase of GPU usage. It also doesn't show an option to change my compute device in the system area or whatever 

However, when I switch to Cycles Render, it gives me the option to use my GPU, but not when I am in normal Blender Render. Is there a way to fix this or is it set like this for some reason?
GPU Rendering is not available for Blender Internal  

Blender Internal engine was designed to use CPU long before GPU rendering was available. To make the use of GPU in Blender Internal it will be necessary to rewrite the code of this rendering engine in order to adapt to different computation technology, currently it is not in the priority of the developers, but hopefully in the future.
