1080p
What is factory clock ?
Factory overclocking is overclocking done by the producer of the aftermarket card. An MSI GTX 1080 may be clocked at a different speed than a Zotac or Palit one from the factory.
If you only game at 1080p, 1080 is way overkill. Get a 1070, much more for your money.
If you are planning to upgrade to 4k soon, you should put in the extra money for a 1080ti...
