Not a deal for everyone but if you are in the market for a 1080ti, this is one of the very fastest in the market (pretty much only beaten by the Zotac Amp Extreme). Same card is £698 at Overclockers and £719 at Scan.
Most Founders Editions seem to start at around £640 so for a relatively small premium you get a good boost in base clocks and a 4 year warranty (requires registration).
On backorder and due to ship tomorrow (19/05) at the time of posting, hopefully this will help someone get some nice 4k gaming.
