On friday i will have all my new components to build my new pc with the exception of my x1950 pro which i will be ordering friday for a saturday delivery. The question im asking is do i build my pc and install windows etc by using my current nvidia card then just install my x1950 pro when it arrives saturday or do i just wait till the saturday to do it all. Im not sure if installing a nvidia card then installing an ATI one will cause problems. Thanks for your help
