The 1600 series falls between Nvidia's current generation of graphic cards, the 2000 series, and its previous generation, the 1000 series. This makes the 1660 an excellent midpoint in terms of price and specs. Performance-wise the 1660 is comparable to the GTX 1070, but functions on a newer architecture that draws less power.
You can pick up the more compact version for cheaper – prices are around the £259 mark: Ebuyer has a Zotac-manufactured option for £259.98, while on Scan, you can find an EVGA make for £268.99, down from its £299.99 RRP.
