perhaps you need to check with your nearest or largest local retailer, because EOL-ed products still have the minority chance to find it.

and yes, there is a lot of differences between GT720M to GT750M.

Hey there I would like to ask for some recommendations for a laptop, and I do have many requirements, please don't judge!

1 - I would like the build to be similar to a MacBook Pro, thin, but it doesn't have to look exactly like a MBP.
2 - The screen should be at least FULL HD, meaning 1080 p and above
3 - The laptop has to be lightweight, around 2-2.5kg and below
4 - The battery life should be good, at least 6 hours and above.
5 - It has a decent graphics card

I would be really happy if someone could find me such a laptop, as it is very difficult to. Anything except a Razer Blade please!
