SYSTEM TYPE 1 << Try to stay clear of this model if you can, the cpu is dual core only and the video card is only a 640 which is pretty weak. system type 1/2/3 is not a good naming scheme and no one will know what you are talking about, so just don't use these names in general) (don't start using these names for the system, i just made them up to tell them apart. So you can really break these down to 3 different types of system. = upgraded gpu noted by sticker over gpu spec Only ever found 402 with upgraded gpu, unknown what origional gpu is
