Gigabyte GTX 1060 6GB WINDFORCE OC with ability to turn down its fans when under light load and enough performance for GTA V, Rust, etc at 1080p.
ASROCK B150M Pro4 gives a lot more than equivalent price boards from other brands with a down side in no USB2.0 at the back for key/mouse but your case will be able to take care about that.
It is the SuperNOVA G2 that is the really good one. The NEX is just ok. And 650W is overkill for such system so I swap that out for a lower capacity so that with £3 past the £800 budget, you can add the 1TB HDD in.
