i just got my new Zotac GTX 970 and blender 2.73 but i'm worried about my cylcles results. My other card was a GTX 670 OC, so theoreticly i should achieve 50-100% faster rendering times. Sadly the increase turned out to be around 10-20% in direct comparison. My question is: Could anybody tell me if this is normal at the moment; maybe caused by a lag of optimisation? Is someone achieving better results? I'm really worried if the card is worth the extra money :/

I am using: Win 8.1, i5 3350p, 8GB

  • $\begingroup$ This always depends one the scene, my 980 is approximately 2.5x faster than my 660. For more samples see mad-creations.nl/blenchmark $\endgroup$ – stacker Jan 14 '15 at 20:53

    $\begingroup$ have you tried using both cards in tandem? The more gpus the faster cycles will render... $\endgroup$ – user1853 Jan 14 '15 at 22:58
