It looks as though we are coming towards the end of an era as there are now only 2 machines with GTX295s in the top 100 machines for Seti (one of those is mine and it's still just quietly plugging on). I can still remember the days when these cards were stacked through the top 100. |

Not progress. Good Marketing. GTX295 versus GTX690. |

I bet that there arn't that many of those old cards that are able to run any more. Cheers. |

The 690 is probably running 2 or 3 wu per gpu... judging by that computers RAC I would say it is. Do you Good Search for Seti@Home? http://www.goodsearch.com/?charityid=888957 Or Good Shop? http://www.goodshop.com/?charityid=888957 |

And then there's this rig of mine doing not much less than Lionel's ATM but I bet that it's using a lot less power and producing a lot less heat (sorry Lionel but I bet a similar rig with a pair of GTX 660Ti's would be better than 2x GTX 295's). [Edit]The GTX 660Ti's will each be doing 3 w/u's at a time of course. ;-)[/Edit] Cheers. |

The 690 runs easely 2 WU at a time per GPU (so it actualy run 4 WU per card). It could run 3 but makes little diference in performance so in it´s case 2 is better than 3... unless you have a very slow CPU to feed the GPU, something that makes little sense if you have this top of line GPU. |

Yes you are probably right about the power side of things and the capability of the 660s vs the 295s. I thought it might be interesting to see how many 295s were left which is why I went and had a look. I will eventually phase the 295s out though. The issue for me will be do I cycle cards down, or just replace those with new or second hand. cheers from Melb. |

Almost all of my 295s have succumbed to old age and hard work. I have 1-1/2 left running in a rig with two of them, of which one has lost a GPU core. My best rig used to sport a pair of them, but, they have passed on. Meow for the 295s!! "Freedom is just Chaos, with better lighting." Alan Dean Foster |

It is good to see the progress of newer hardware. The servers are not as happy I am sure, but we can blow up that bridge when we come to it.
