Question Why is 960 a lot more expensive than 970?

Ah I see, we get a lot of people who would never come close to saturating EVO speeds, so I have to ask.
For computation that wont really deal with storage unless you are writing and transferring data around a lot, the actual computational work is not really storage dependent.

That being said, the 970 PRO/EVO has outstanding endurance, which depending on your use, may be required.
