Hi there - next time provide a link for people browsing your thread.
In terms of performance it depends on what you are using your machine for. Computers have many functions today and have a variety of uses. Neither of those laptops are good and have considerably outdated specs by modern standards. With that said, the ASUS is probably your best choice. If you provide more information I would bet this board could serve you better as to what is the best choice for your new laptop.http://www.cnet.com/laptops/asus-eee-pc-1005hab/4505-3121_7-33938000.htmlhttp://www.cnet.com/laptops/gateway-450sx4/4505-3121_7-31581099.html
