Where is a store I can buy good quality gaming laptops that use Windows 7?

I recommend you buying it online, it is much cheaper and it will delivery to your home, you also get warranty, and there is one site, the more reliable and prestigious for purchasing almost everything online, the #1 around the world since over 16 years is http://www.amazon.com/?_encoding=UTF8&tag=gananci-20

If you want a good gaming laptop, I think it would be better to buy it online. I'd recommend an Asus G series. Avoid Alienware, they look cool and all, but they are ridiculously overpriced and I know a couple of people irl that have had a horrible time with them.

Windows 7.1 I am not familiar with that. I have windows 7 Home Premium 64-bit. Check at wal-mart, Office Depot, Best Buy and www.newegg.com

Does it have to be a physical store? I recommend the Alienware M14x: http://www.dell.com/us/p/alienware-m14x/pd.aspx But you'd have to buy it online. I'm not sure if you can find it in any store (I could be wrong).

The best 2 stores i would have to say is bestbuy and walmart, Bestbuy would be a pro at finding the right computer for gaming if you tell them what exactly you are looking for

Check a local computer shop, and talk to them. They'll either have some powerful models, or be able to point you to where you can get them. Most corporate stores stock crap which, while works well for the average consumer, are crap for gaming.
