KitGuru published a review on the MSI Infinite X (8700K & 1080 Ti) System
A quote from the article:
MSI Infinite X is a pre-built gaming PC that you can pick up locally, provided you live somewhere near a John Lewis department store. The hardware is a classic combination of Intel Core i7-8700K and Nvidia graphics and naturally enough both the motherboard and graphics card are manufactured by MSI.MSI Infinite X (8700K & 1080 Ti) System Review
There are three versions of the Infinite X on sale here in the UK that are differentiated by the choice of graphics card, which affects both price and performance. At the bottom end of the scale we have the 8RC at £1499 with GTX 1060 graphics. For an extra £200 you can step up to the 8RD at £1699 with a GTX 1070 GPU, or you can push the boat out the whole way and go for the 8RE at £2100 with GTX 1080 graphics.
So there are three models of Infinite X, however the sample we received came with a GTX 1080 Ti graphics card which means it is unique, and also means it is not representative of the Infinite X you might buy. Put it this way, the Infinite X we have here looks like the best case scenario for this family of PCs.
