Best places to buy a gaming laptop

The processor is fine for TS3; other people play on it without any trouble. My comment was more about futureproofing, since you might want to run other games on your computer, and those might run much better on a newer CPU. The HDD will also run TS3; it'll just be slower than an SSD, probably by a significant margin if you have a lot of custom content. But if you get frustrated in a year or two with the slowness, you can get the HDD replaced with a large SSD. A 1 TB model might cost you $110.

Also, as igazor said, the objection to Alienware is the price, not the hardware, which is generally of good quality.
