Need A Laptop Under $800?

I need a new laptop to replace my old one. I need one that can run games like Minecraft, LoL, Starcraft 2 on medium settings would be good. It can go a bit over my budget range.
Any suggestions? You can post links it would be helpful, thanks.

I got a laptop with Google Chrome O/S that is much faster than my 2-year old Windows-based laptop for $123 (with a warranty). However, it does not run anything that requires Windows. So, for example, some games would not be able to be installed. However, basic web browsing is very clean and swift.

Why would you want to buy a new laptop to play Minecraft, that can be played on any 14yr old computer with 512 megabytes of ram in it, In fact it can be played from a Usb jump/flash drive or SD memory card… Without it being installed on the hard drive… If you used the right operating system (Not Windows) you can play most of the games on your old laptop.
