So I have a really bad laptop, it's a Toshiba. It has an i3 processor and not much memory. So I was wondering is it possible to upgrade my laptop? I would like to put an i5 processor in there and maybe some more memory so I can at least be able to play Battlefield 3. Because my dad doesn't think I can build a computer, to be honest I've learned quite a bit about Computers over the summer. Also, computers are expensive so if you can help me out and answer my question that'd be great. Thanks!
