Is it possible to imput a better cpu?

Hello, I just bought a brand new Toshiba Satellite C675D windows 7 laptop and I am really interested in very light gaming. My old computer ran very low demanding games fairly well, but I wanted better FPS and speed, so I got the laptop listed above. I now know that this laptop isn't for gaming, and so are most laptops. Everything about this laptop is very good except the CPU. The CPU does not even meet the least requirements for games that I used to play on my old PC. So I was just wondering, would it be possible at all to upgrade my CPU to anything better? If so, what kind of CPU? I called Laptop stores and they said that a laptop can't have replaceable parts as a desktop does. Also if you could recommend what I should do or get to run games with ease, that would be great! thanks in advance!
