The price to performace between the 970 and 980 is not too much of a difference to justify the money required to buy the 980 as it does cost quite a bit more, if you were to buy a 980 I'd recommend the 970 but back to answering your question. Yes, it is worth the upgrade. BUT that comes at other factors as well. What is your monitor setup? 4k = upgrade, 1080P = Dont, or do. This depends alot on other factors such as 1. Is the performance enough for you right now? 2. Are you able to maz out the settings that you have? 3. Earlier said, What monitor setup do you have? 4. What games do you plan on playing? These factors are somewhat vague and you can talk alot about other things as well but this is a good start There is quite a big difference between the 680 and 980 so if I were to give advice to a friend it would be sure, upgrade if you have they budget.
