I am planning to get an nvidia geforce 8800 gtx graphics card but it has two dvi-i outputs. My "new" 20 inch Dell monitor only has dvi-d and vga inputs (If its new, it should have DVI-I). How can I connect the 8800 gtx to my monitor? My monitor has a s video input and the gtx has an s video output. Could I buy an s video cable and plug it in that way? Would I lose any graphics power if I did this?
