Laptops have a good reason for existing, which DOES NOT include for game play. They are far too expensive to replace every three years or so, when new games bypass the older laptop hardware, particularly the GPUs. Desktops start out less expensive and do not have to be replaced, but can be upgraded in place over a period of several more years, until the overall design becomes outdated.
I have a PC here by my shoulder, in a ten year old enclosure, with a new power supply, a five year old mainboard, only six GBs of DDR3 RAM, and a three year old GPU, I use it every day. The only truly "slow" part about it is there is no SSD at all in it at present.
