Ok I was going to by the liteon 12x dvd burner with a cdrom speed of 48x, but then I heard about the dual layer where you can copy more of a dvd on one disc. Is it worth it to get this? For dual layer the 8x is $100 and the 12x one single layer was $80, but the dual layer seems more appealing. So my question is... is 8x going to be fast enough and will the 40x cdrom speed be good for games such as doom 3? thanks!
