I know how to get the specs, I am requesting a speccy to look at the temps, services running, and hard drive space on that machine.
The Toshiba laptops tend to run warm, due to the way they did the cooling for the CPU & GPU. I have this cooling pad http://www.amazon.com/gp/product/B002VC9F0Q/ref=oh_details_o02_s00_i00?ie=UTF8&psc=1 Because otherwise my Satellite C850D would be pushing 131ºf if I didn't. With the Cooling pad, it keeps the temps down to around 110.
Yes temps can be an issue, but most likely I am going to say that it is due to the type of GPU they have installed onBoard. The Satellite C55-Axxxx Series is not considered a gaming type laptop. It is more of an everyday or Economy laptop. These are what are considered Performance/Gaming laptops under Toshiba's available systems http://www.toshiba.com/us/customlanding.to?page=Satellite_P_Series#25+216+366+367+368+369+4294946613+4294946643%7E100%7E0%7Ep_Featured
The Qosmio X series is the top of their line, when it comes to wanting something that can handle higher spec'd games, that require a lot of horsepower. http://www.toshiba.com/us/computers/laptops/qosmio
Even with mine & my son's C850D series Satellites, which both have the same specs, but one has a platter drive the other a SSD, even playing stuff like Minecraft, etc. will lag on our systems. Now of course I could load up a Linux distro, and blow Windows 8 out of the water, and get rid of the lag, if I really wanted to.
Personally 8.x sucks when it comes to playing any type of games on it. Very well spoken on other forums that 8.x was not designed with gaming in mind.
