here is a setup that would be a grate computer for gpu crusher when it comes out also are some other setup that are good this is to help som people who are not sure what works with what but can built a computer, all prices for from newegg.com i always use them for computer hardware gpu high price best speed money can buy EVGA GeForce GTX 280 01G-P3-1280-AR Video Card - Retail price = $374.99 * 4 COOLMAX CUQ-1350B 1350W ATX 12V V2.2 price = 300 * 1 MSI K9A2 Platinum AM2+/AM2 AMD 790FX ATX AMD Motherboard - Retail price = 150 * 1 OCZ Platinum 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 1066 price = 29 * 2 Western Digital Caviar SE WD800AAJS 80GB 7200 RPM SATA 3.0Gb/s Hard Drive - OEM price = 36 * 1 AMD Phenom 9600 Agena 2.3GHz Socket AM2+ 95W Quad-Core Processor Model price =120 * 1 Sunbeam Silent Storm case price = 50 * 1 LITE-ON Black SATA DVD-ROM Drive Model iHDS118-04 - OEM price = 18 * 1 grand total 2231.96 more setups to come i would not reamend this one it just the most gpu power you could get it will go down fast around the time the gpu client hit main stream |

nice box . I'm an AMD enthusiast and even I'll admit that even with that nice rig you'll still never catch a intel 6600 thats OCed to 3.2ghz In a rich man's house there is no place to spit but his face. Diogenes Of Sinope |

Well if you want seriously expensive CUDA cruncher try on of thease :- http://www.nvidia.com/object/product_tesla_c1060_us.html available at TigerDirect for `only $1700 http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=4259469&CatId=4044 the nvidia site is quite interesting, but a tad costly. |

I see "power usage" and a 95 watt CPU. While I too prefer AMD, there are dual core Penryns at 25w TDP. Edit: I'd also eliminate the DVD-ROM and anything else I could find from a crunch-only system. If you're going to do something else with it, then that's different. |

yes but for gpu computering you need one cpu core per gpu card |

yes but for gpu computering you need one cpu core per gpu card Why? Folks are reporting CPU seconds required to complete a result far below the elapsed time. Can't we expect a core to tend to the needs of more than one GPU? |

well idk i can't test this at this time but look at how it doing thing most likely no buy unknowen that this time it can be done but will it is in q here |

well idk i can't test this at this time but look at how it doing thing most likely no buy unknowen that this time it can be done but will it is in q hereI'm not sure I got your thought, so I'll paraphrase my understanding and echo it back for comment: Boincmgr (or its equivalent) sees cpus, not GPUs, so will only start a number of BOINC threads equal to the number of CPUs reported? Thus if one has fewer cores than GPUs, some GPUs will necessarily remain idle? If that is true, it seems something the GPU ap developers might want to find a workaround for--though what with the fad for multi-core CPUs, and the return of hyperthreading, this may not be a very serious limitation, except for the failure to use the resources of the CPU proper. |

you mostly there boinc runs it as a coprocessor so it need a cpu even if it not fully used because boinc is not smart to see it not being use so there no easy why to fix this with out redoing the whole boinc cpu management part of the programm |

Well if you want seriously expensive CUDA cruncher try on of thease :- AMD has a processor card also. http://www.tigerdirect.com/applications/searchtools/item-details.asp?EdpNo=4259680&csid=_21 Daniel |

Well if you want seriously expensive CUDA cruncher try on of thease :- at this time that will not work with seti because cuda is a nvidia program so at this time only there cards 8200 and up will work |

you mostly there The BOINC developers are redoing the logic, the project now specifies what it needs as a GPU plus a fraction of a CPU. Not all logical possibilities of that have been added yet, but if a project specified 0.1 CPU needed it ought to be possible for the BOINC core client to schedule up to 10 GPU tasks with one CPU. Part of the problem is that the BOINC developments have been aimed at GPUgrid, which specifies 0.9 CPU for a task. That has inhibited deeper thinking about the possibilities, particularly since the actual CPU used for those tasks is very small on Linux but something like 0.4 on WinXP. And nobody seems inclined to notice that 0.1 CPU for a Nehalem at 4 GHz is likely to be 0.8 CPU or more on a P4 running hyperthreading at 2.8 GHz. Joe |

also with cuda one app can use the power of one gpu and at this time it a max of 4 gpus in one computer so the best crushing would be one core feeding all the gpus and 3 cores doing it the old way but to do that is more about boinc then seti |

HD 4870 X2 XOC outperforms the NVIDIA... If we have a app to use it, prerequisit BONC must handle it too. heinz :-) D5400XS V8-Xeon |
