Hot on the heels of the other 1080Ti cards today (FTW3 / Strix - £666, FE £582) here's another AIB card, but this time cheaper.
may help you to determine the relative worth and merits of the FTW3/Strix versus the SC2 and FE cards.
TLDR: There's nothing between them performance wise at all and only a little variance of temp and some acoustic differences.
If you want an aftermarket card for lower temps than the FE offers, I'd suggest this one over the FTW3/Strix based on price alone.
27cm long in case you were wondering, Strix is 29.5cm.You need to click 'other sellers' to see the Amazon price listed.
I've since found a cheaper deal, listed here @ £608: http://www.hotukdeals.com/deals/evga-geforce-gtx-1080-ti-sc-black-edition-608-33-amazon-2735432
