Same card as the more expensive non-black 1070 SC. Main differences are that it has no back plate and is a slightly different colour (which are quite minor)
All reviews indicate this cards runs cool and is quiet. 3 year warranty.
EVGA are widely regarded as having the best customer service in the industry. They also have a UK RMA centre which usually means a 1 week or less turnaround time.
Finally, they offer a 'step-up' program. This allows you to (within 90 days of purchase) buy a newer Nvidia 1000 series GPU by trading in your 1070 and paying the difference. So for those of you wanting a GPU now, but eager to get the rumoured 1080ti, this may be the card for you.
