While we want our laptops to become thinner and lighter, we don’t want to them to lose their ability to display the best possible graphics. Unfortunately, for now, that just isn’t possible. But there is a solution. Meet the Razer Core X External Graphics Enclosure, your MacBook and/or Ultrabook’s new best friend.. Through its fast Thunderbolt 3 connection, the Core X is able to deliver plug-and-play graphics using the latest PCIe graphics cards from AMD and Nvidia. It looks good and runs great. The inside features standalone cooling and vents that are optimized for thermal performance, so you won’t have to worry about it running too hot. Best of all, you are able to upgrade the card inside whenever, so no worries about it becoming out-of-date.
