I recently found a really cool new website. I was wondering what was the most powerful custom laptop and it turns out its the Eurocom Panther 4.0. The website I found lists and ranks the most powerful custom laptops. They provide table spec comparisons of the basic and fully upgraded versions of each laptop model. The website is called http://listofmostpowerfulcustomlaptops.weebly.com this is a really good site to get specs from. They also have a pages that do lists for other specific laptop components. For instance they have a page listing the most powerful laptop processors. They also have a page that does a list on most powerful video cards. They also have a very interesting tech blog.
