Looking for a budget upgradable thin, gaming capable laptop.

[Guest]

I'm looking for a laptop that is thin and capable for gaming but on a budget. Anything with a gpu better than a 540m and cost less than $600-800

Like an Acer 5750G but better.
Also upgradable like the 5750G.
I don't care about weight
