I have been using this laptop in i7 3630Qm and GT730 configuraiton and I wrote a full review here http://forum.notebookreview.com/acer/717456-acer-aspire-v3-571g-736b8g1tmaii-review-awesome-gaming-laptop-ips-screen-those-budget.html
In short: it's a good laptop for the money that has a fantastic, class-leading IPS screen (it is beautiful), and will play most of my games (RTS) at mid-high details often at 1080p resolution thanks to the powerful CPU which powers through anything I throw at it.
Build quality is good and solid (much better than my old Dell), speakers are "ok", battery life is distinclty average, and the keyboard is imo quite stiff and difficult to type on, requiring a lot of pressure for keypresses, which isn't ideal for lots of typing. However, stick in a full-size external keyboard (like you should whenever possible when typing a lot) and all those problems dissappear.
All in all though, it's a great deal, and you won't get better for the money. No laptops of this price range have such an amazing screen and good overall spec. :)
