Re: i just cant decide on what to do
The video card will not use DX9 effects. You can install DX9c on any PC with any video card. But you must have a video card that is DX9 compatible for the DX9 effects to work. Games are coded to run with DX8 and DX9. Future games will probably be coded for only DX9 and DX10 so your current DX8 card will not be able to run them. As I said, DX8/9/10 is the actual architecture of the GPU on the video card. There is no way possible for software to change that. It is part of the hardware.
