Upgrading the GPU in your gaming laptop is normally not an option, but external graphics card cases allow you to make that change, so long as you have a fast enough Thunderbolt/USB port. The new Razer Core X V2 makes that upgrade easier than ever, though you’ll need to supply the graphics card yourself.
Even the most powerful options in our best gaming laptop guide can’t hold a candle to the performance of a desktop graphics card, thanks to the thermal limits of most laptops, and the fact that Nvidia made its laptop RTX 5090 far less powerful than the desktop version. With external GPU enclosures (eGPUs) such as this new one from Razer, though, you can get close to true desktop gaming performance.
