In addition to your new gaming laptop Razer has also unveiled a device called Core X. This docking station to create an external graphics card.
Want to remind you that Razer already have a similar model of the Core v2, which was released last fall (and the original model came out in March 2016). However, that costs $ 500, and a new model — $ 300.
This novelty into something even better. For example, it allows you to set translative graphics card, whereas the old model only can fit dual-slot model. In addition, the power supply, the new model is 650 watts vs 500 watts for a more expensive version.
Of course, there are downsides. Is the lack of ports (not counting TB3), larger sizes (330 x 160 x 60 mm) and the lack of the original lighting. But if the difference is 200 bucks, I think the choice is obvious. To connect to a PC, of course, use Thunderbolt 3, which is the only connector on the docking station except for the power.
