EDIT: Also if you are a gamer, avoid the Nvidia 555M card, or anything with Optimus. It is 'battery saving' tech which constantly forces the games to use the i7's instead of the card... and there's very little you can do about it. drives me up the wall.
First off this is medions gaming range so I think the build quality would be better. Of course it wont be as good as Asus or Sony or Toshiba but you get what you pay for.
Secondly the GT555m is fine card and nividas optimus tech is easy enough to use. Most people I know who have it, say it'll switch to the GT555m just fine when it needs too. Though they also say it will sometimes revert to the integrated card like you mentioned in certain games, in this situation all you have to is add the particular game to the cards whitelist and it should work fine then.
I can assure you, your experience with optimus is the exception not the rule.
