I got a gaming laptop at the end of 2012, hoping to use it to play Steam games on the tv (at the time, I was thinking F1 2013 on a 60", yes please). It worked out rather well, but I didn't care for it for any games other than controller ones (needing to keep the screen open, having to have an extra mouse and keyboard, etc) but games with the controller were awesome. Regular games using the laptop as a laptop instead of a set top were all pretty good.

That experiment didn't last very long, the laptop became my 'no games installed, do your damn homework' computer. I am impressed with how quickly it renders and does the bullet dynamics compared to my desktop (rocking a Core i7-940 still).
