This is not for someone to daily drive. You’ll probably get better performance duct taping and raspberry pi to Bluetooth keyboard and 7 inch pi display.
Edit: It’s an article about how a company is going to assist in providing RISC 5 dev boards to framework. It’s not about a consumer ready product with a dedicated GPU.
The SoC itself only has two PCIe 2.0 lanes on separate interfaces so you can't use both for the same device, and one is shared with the USB 3.0 interface.
That's not even enough bandwidth to drive an entry-level notebook GPU from over a decade ago. Seriously: the GeForce GT 520M, launched January 2011, wants a full PCIe 2.0 x16 interface. Same with the Raedeon HD 6330M. You could probably get away with just 8 lanes if you had to, but not only one.
The other commenter wasn't kidding by saying you could get more power out of a Raspberry Pi 4. It's even mentioned in the article.
