Leadtek sells two versions of it's Geforce2 Pro card, one of which is the enhanced version. When I read the specs of the enhanced card, it said "The New Enhanced WinFast GeForce2 Pro 32/64MB is the only one in it's class to use 5.5ns DDR memory." That really confused me - they are absolutely right, all other Geforce2 Pro cards (including their nonenhanced card) use 5ns memory. What's going on?
