Was thinking of upgrading to X5680's (3.33ghz) but the changes in the chips after westmere makes it not worth it. The latest chips are so efficient. The i7 5820K @389 is cheap for a hex chip. I looked at the specs for the difference between the X5670's and the X5680's. I think you are wise to stick with the x5670's. They might not be quite as fast, but they have a much lower TDP. This saves on your electricity and should make your cooling less costly also. Cheers

Thats the reason I got them, lower power consumption. Pretty impressive the new 8 core crunches around what my dually can do. I could build a 5820k complete system cheaper than the 8 core chip. Will see if the price drops in the summer to see if I can afford the 8 core.

Congratulations are due to Bearcat on his 20 year accomplishment for MCM1 and to Mclaver for his ten year milestone for UGM.
----------------------------------------Bearcat, do you think you will make a 50 for MCM1 ? I may have just enough time to get that. Cheers

Thanks. I switched over to gnome to work on 5 year badge while i wait for ebola to crank up. Need less than 1 day for a bronze badge on ebola. Good luck going for 50.

My guess is not overclocked... Intel Core i7-5960X @ 3.00GHz: 15948 Intel Xeon X5670 @ 2.93GHz: 8281 Got this comparison off of cpubenchmark.net The extra 2 cores (4 threads) and IPC improvements over several generations gives the i7-5960x an almost 2x performance increase over the x5670. Since you have 2 x5670's in that system, both systems should be comparable in performance. Here's an AMD Opteron 6180 x2 system before I shut it down for vacation after Xmas. Just happy it can still keep up with the Intel systems... guess it averages somewhere between 70-90k ppd. 12/27/2014 0:023:19:19:49 94,897 158 12/26/2014 0:029:03:14:58 117,252 196 12/25/2014 0:023:12:37:06 74,227 104 12/24/2014 0:020:05:20:07 67,515 87 12/23/2014 0:022:21:07:07 95,570 191 12/22/2014 0:027:19:31:52 123,326 248 12/21/2014 0:024:19:04:44 92,574 175 12/20/2014 0:021:13:38:34 68,550 90 12/19/2014 0:020:02:19:39 79,534 140 12/18/2014 0:022:08:45:43 78,684 158 12/17/2014 0:023:09:19:07 99,090 182 12/16/2014 0:025:04:54:08 97,735 175 12/15/2014 0:024:16:25:23 68,727 103 12/14/2014 0:026:01:28:19 67,669 82 12/13/2014 0:023:19:01:24 66,833 88 12/12/2014 0:022:19:08:08 62,013 81 12/11/2014 0:023:15:03:47 66,261 83 12/10/2014 0:022:17:31:05 70,926 90 12/09/2014 0:022:03:54:31 83,856 97 Enjoy the warmup for a few days guys... It is actually overclocked to 3.7 GHz, it is averaging 10,360 Boinc pts per day, the highest ever 13,271. I wonder why I am not achieving the performance you are getting. It runs 24x7 with nothing else on it under Win 8.    [Edit 1 times, last edit by mclaver at Jan 21, 2015 3:22:28 PM] |

Keep in mind its comparing 24 real cores to 8 real cores (+ HT). For yours to be doing the same amount of work (or nearly so) is impressive.  |

For the past week, I've had the AMD system back up and running to help get my 10 year on CEP2. Surprised that it's been able to run 24 CEP tasks at around 95% efficiency (cpu vs. elapsed). Its running a single 120gb Intel SSD 320 series.
----------------------------------------I'd like to get one of the i7-5820k 6 c/12t systems the only thing is the DDR4 prices are so high. Maybe will end up waiting until broadwell or skylake comes out to upgrade the intel systems. |

Get a i7 4930k. Uses DDR3. Mine crunches pretty good. Not much difference than haswell version.

Interesting thing is the 4930k is more expensive by about $200 than the i7-5820k. I guess Intel is subsidizing the price of the DDR4 by bringing the 6 core cpu prices down.
----------------------------------------Not a bad deal, but I don't have much expendable income at the moment. |

Not a bad deal, but I don't have much expendable income at the moment. I don't either or I would have that 8 core crunching now. The 5820k is pretty cheap for a hex. I need to win the lottery so I can build a dual xeon 18 core/36 threaded monster! 72 threads on one machine crunching would be friggin awesome.
