Can i run Tomb Raider 2013 on my laptop ?

I don´t remember, but of course you can play later in a desktop in your home ;)

Also don't believe the canyourunit crap site, the best benchmark is "first-hand" experience on your device itself, also seeing how amazing Square Enix PC releases are (namely Deus Ex and Sleeping Dogs), I'm positive it'll work well on 800x600.

CYRI said I can't run Sleeping Dogs on my old i3 laptop but it ran the game fine on low-med.

You could also download a torrent of TR and see how it runs, if you like it buy the game, later you can just move the pirated files to steamapps/common/Tomb Raider and begin the download on steam, it'll discover existing files and download any corrupted/missing (or sometimes replace modified) ones. Atleast that's what I did when I had an i3.
