Wow. I think the 6ks are good. But which one is better, 6870 or 6850? According to the graph on your link, sometimes 70 is better, but sometimes 50 is better.
I have few more things to ask:
- Why you prefer 6Ks over 5Ks?
- How 6Ks performed compared to gtx 460 or even 470?
Thank you for your great help
