Alienware - Flashy, high priced and easily breaks down. My brother bought a $3500 Alienware laptop with the works and it broke down multiple times and had to be shipped to service.
PC - Stands for personal computer. Basically, any computer you own or use on a daily basis. Therefore, it's pretty much everything.
Mac - Gaming? Haha, no.
Toshiba - I really don't know anything about Toshiba. From the gaming laptop (And they only sell laptops, no desktops) page, they're really pricey.
Dell - Although they sell laptops and desktops, most of the time they're for business use. Alienware is owned by Dell, for the record.
If you need a gaming laptop, there is an easy deal for a good one on Best Buy.
