I bought this laptop with Core i3, Nvidia GT 720M, 4GB and without operating system. It cost only 399€ ($517) in Estonia, but for that price it is a very powerful computer. Normally, for that or even way higher price, you can get only Intel integrated graphics card or some weak Radeon card, but this computer lets you to play most of the latest games. With Core i3 and 4GB ram, there is only few things you can not do with this computer. In Addition, while using it, you can feel that computer is strong (which is not very common these days), especially the hinges. Keyboard and touchpad are comfort to use, numpad keys and function keys instead of f-keys were pleasent surprise, at least for me.
But there is some problems too. Firstly, I expected a bit longer battery life than 4 hours and secondly, there is some overheating problem (like all computers with Geforce 7xx series GPU). While playing Mafia II, the GPU temperature can reach up to 90 degrees Celsius, which can harm the motherboard. But if you buy a cheap cooling pad and remove the bottom part of case, the problem is solved (GPU temperature never reaches 50 degrees). Otherwise, the cooling pad does not help, because there is no air hole in case near GPU.
If you don't see the overheating and 4 hour battery lifa a big problem, this computer is highly recommended.
