If you want the same amount of Maxwell Streaming Multiprocessors and ROP units as a GTX 980 as well as that last 500MB of RAM to run at full speed then you will need to pay for a GTX 980.  One choice is Gigabyte's GTX 980 G1 Gaming which will cost you $580, around $240 more than a GTX 970 but the premium can be worth it if you need the power.  [H]ard|OCP took the already overclocked card from a boost GPU frequency of 1329MHz and RAM of 7GHz all the way to a boost of 1513MHz with RAM topping out at 8.11GHz.  That overclock had a noticeable effect on performance and helped the card garner an Editors Choice award.  See it in action here.

"Today we have the GIGABYTE GTX 980 G1 GAMING, which features the WINDFORCE 600W cooling system and a high factory overclock. We will make comparisons to the competition, find out how fast it is compared to a GTX 980, and you won't believe the overclock we achieved! We will make both performance and price comparisons."
