The first gaming laptops with NVIDIA RTX graphics cards are launched. Most of the time, though, you stick to the graphics card that you choose when you buy your computer. Unlike gaming desktops, gaming laptops typically do not have upgradeable graphics.
Premium computer company Eurocom, however, sells laptops with upgradeable graphics, and the company has announced that some of its "mobile supercomputers" are now available with NVIDIA RTX 2070 or RTX 2080 graphics.
The GPUs are on replaceable MXM graphics cards, so you can opt for a cheaper card today and switch to a more powerful option later. 
To call these computers "mobile" is probably generous. The smallest part is a 15.6-inch laptop that weighs 7.5 pounds and is half an inch thick. Still, it's probably easier than hauling a desktop + monitor around.
However, they have desktop-class hardware. The computers are available with an Intel Core i9-9900K processor, a 95-watt octa-core chip. They support up to 190-watt graphics cards with options from NVIDIA GeForce 1060 to GeForce RTX 2080 (or NVIDIA Quadro P5000 for professional workloads). Some models even support two GPUs.
Other outstanding features include support for up to 128 GB of RAM (thanks to four SODIMM slots) and support for multiple storage devices (each model has at least two M.2 slots and two 2.5-inch drive bays and support for up to 4K screens The laptops also have replaceable batteries, something you will not find on thinner and lighter models (and something you probably need on a computer with hardware that can be discharged) a laptop battery in no time),
Not surprisingly, these computers are not cheap. Pricing starts at $ 1610 for a model with a 15.6-inch 1080p display, a Core i7-8700K (or 8700T) processor, NVIDIA GeForce GTX 1060 graphics cards, 16GB of RAM, and no storage or operating system ,
