Hi All- I'm interested in downloading the free Google Earth Pro. I'm not sure if I meet the Graphics card requirement of: "DirectX9 and 3D capable with 256MB of VRAM ". My card (as seen in sig below) is a "ATI Radeon HD 4850 w/512MB". I cannot find a comparison between their recommended card and what I have & the relation to running Earth Pro? Is my card compatible? If my card is compatible should I uninstall my present Google Earth 7.1.2041 before downloading Pro?
