How i see my laptop graphics type is the gddr3 or gddr5

How about posting the Laptop model. As pointed out if using an iGPU such as the New sandybridge CPUs, then it's a mute quesstion as answ = nethier.

Does it make a difference since in many cases it can not be changed, unless you can change the dedicated GPU - And that is only if the laptop has a dedicated GPU, Hense reason need the make/model.
