Microsoft's cheapest Surface Book is joined by a new dGPU model

The Surface Book range just keeps on growing. After the initial launch, Microsoft added a 1TB model and today another makes its way to the Microsoft Store. Bringing the number of options up to seven, there is now a 128GB dGPU available.

This means that Microsoft now has a discrete GPU Surface Book in all four capacities: 128GB, 256GB, 512GB, and 1TB. Apart from the addition of the dGPU, the specs are the same as the entry-level Surface Book, and $200 has been added to the price.

$1,699 gets you the 128GB, Core Intel i5, 8GB, dGPU variant of the Surface Book. As this model has just been added, it offers the best opportunity for anyone keen to get their hands on a Surface Book as soon as possible. While there are wait times of several weeks on all other models, this new one is currently shipping from 26 October.

The new addition will also come as great news for would be Surface Book owners who had been looking for a dGPU but didn’t like the idea of shelling out $1,899 for the privilege. If you want to get hold of one, head over to the Microsoft Store -- although Microsoft is still to release benchmarks to back up its performance claims.
