Wow, thanks, I am glad I asked. I think I'll go back and look some of the Gforce boards again. Does upgrading to a higher end Graphics board do anything to improve the speed of running preview animations in OpenGL. I have a pretty decent CPU processor and memory and at present and In order to preview in real time I have to enable the "skip frames" option or face a super slow preview speed. I guess what I am saying is how much of an effect does the graphics board have on the speed of the Preview mode. I am hoping that shelling out the extra bucks will show a noticeable improvement
