Hm, ok, it looked to me they were running at the same clock speed (1215MHz), so the +50% shaders should deliver a +50% performance.

Thread: Requested advice for hardware
Post: RE: Requested advice for hardware
| AMD used to be the way to go for many years. This is no longer the case starting with Nvidia Maxwell. The best GPUs you can buy right now are GTX 970, GTX 980, and GTX Titan X. |

Thread: New build
Post: RE: New build
| The GPU you've selected is an OEM design card, not a reference design card, which we would never recommend buying for hash cracking. Further, I would strongly recommend the GTX 970 over the 290X. |

Thread: GTX970 - Overclocking GPU
Post: RE: GTX970 - Overclocking GPU
| Mild overclocking is totally safe as long as you keep the temps below dangerous levels (for the most part, under 90C is acceptable.) In most cases it's a bit dumb if you aren't overclocking, since tha... |

Thread: Nvidia GTX Titan X Benchmarks

Thread: Nvidia GTX Titan X Benchmarks
Post: RE: Nvidia GTX Titan X Benchmarks
| The GPU will hang very quickly if the frequency is unstable.
You'd have to do some serious overvolting to get much more of an overclock out of these GPUs. |
