I have a question I just installed a new MSI R7970 LIGHTNING BE Radeon HD 7970 GHz http://www.newegg.com/Product/Product.aspx?Item=N82E16814127736 This does not have customer mac firmware so it has no EFI support but I am having issues with is being seen as a generic 7xxx video card in system profiler. I als o get issues with video card re-drawl issues. When you move windows around the drop shadow leaves re-draw artifacts. (horizontal lines) They go away when you move a window over them. THE QUESTION. How do i get this card ween as a 7970 and maintain all 6 ports working. I need to get rid of the re-draw issues.
