Got mine Sapphire Vapour-x 280x today, works 760khash without too much hassle. 1080/1500 1,13v @ 68 C, fan 68%. Also VRM is at 88 C and 84 C wich i like, the 7970 could easily go above 100 C. I really like the back plate on the GPU, dont know if 7970 vapour-x also had one tho.    |

What's the noise like on these new cards when mining?
Compared to the old 79xx series?

They are the same cards basically...doubt they change much. |

I got an MSI R9-280X OC Edition last week, mines at 740K temp 78/81 C and it's incredibly silent.  |

I think mine is abit louder compared to the sapphire 7970 dual-x i had in my pc before. Might be just the model tho dual-x vs. vapour-x, i really cant say never had 7970 vapour-x to compare it to.

Same as a 7970, probably, it's the SAME card...lower stock voltage at 1.2v vs 1.25v.

Ok so if these cards are almost the same as the old ones (79xx)
Is it better to get the old cards for alt coin mining?
They should be cheaper, right?

There is another high end model coming, which is new, the 290x and 290. Those should mine faster but we don't know pricing and consumption yet (some say 570usd these days, since it's the pre order price at shoblt.com) I'm probably getting one of those, if they do 1000-1200kh/s whilst drawing 300-350w I think used 7950s would be ideal, specially if they hit the 100usd price point. |

I don't think this is accurate but anybody that bought R9-290x can confirm this? |

Seeing that makes me think it might do 800 or more in scrypt...512bit bus, 6.4ghz mem when oced.

800 seems really low for the price, need at least 1000 to worth the price right? |

I think those are non-oc tests. But still it shows the value compared to the old cards. So im thinking if my 7970 works 760, and 290x works 70 more compared to 7970 based on that chart, we should be getting about 840-850khash on this?
Looks shitty to me, you get 2x 280x for about the price of one 290x and you get ~1500khash vs. 850khash for the same $$.

800 seems really low for the price, need at least 1000 to worth the price right? For the same price you can get 7990 and 1300khash+. |

Keep in mind, Toms is doing no O/C, no option flags, it's basically out of the box with guiminer. My guess is that a fully tweaked setup would be in the 950 KH/s range for scrypt. Still, lower than I anticipated. 2x$200 7950s are a better deal.

I really like the back plate on the GPU, dont know if 7970 vapour-x also had one tho.
Can you please show your config file for that khash? I get 600 maximum with my 280X... I could get 700+ but cgminer reporting a huge amount of HW errors |
