Personally speaking I think AMD are far better value for money! And they work really well, just look at my stats, I only run AMD FX8120's/3.1Ghz & FX8350's/4Ghz with HD7770 & HD7850 Some GPU's are paired with Crossfire and work well, a couple of machines are overclocked a little, all the GPU's are o/c'd AMD Every time for ME! Edit - Added CPU Speed I would always buy Intel, because I have to look at my electricity consumption. Intel has very low TDP, AMD doesn't care about it... And on the top of it, Intel's CPU's are doing great job. Cheers  The energy consumtion depends on the application running, in some cases there are actually not that big differens, and in some applications the FX-8350 outperformes the i7 3770. How much faster is the i7 3770 when running the GPU application in HCC? |

No way Simplex, the energy consumption doesn't depend on application running, but on architecture. Intel is keeping consumption low, AMD doesn't care about it. In few months of running AMD or Intel CPU you will find the difference in consumption is huge.
----------------------------------------It is up to you if you will believe me, or AMD-lovers. Just check TDP of CPU's. Just don't believe such fairy-tales saying "The energy consumption depends on the application running"... Cheers  Crunching@Home since January 13 2000. Shrubbing@Home since January 5 2006  |

TDP doesn't reflect real power consumption.
----------------------------------------It indeed depends on type of application and of course on architecture too. SSE/AVX code consumes more power, i.e. running AVX code on certain CPUs can even temporary disable power limiting! One (with enough knowledge) can write special-crafted code that stresses CPU units to maximum. Also, most later CPUs allow to run above TDP limit for certain amount of time. No flame.

OK. This is probably playing with peanuts.
----------------------------------------My i7-3770 + HD 7750 + i5-2500S + HD 6770M running 24/7 + whole iMac running circa 5 hours per day consume +- 30 Euros per month. All the best Simplex with whatever you decide to buy  Cheers and  Crunching@Home since January 13 2000. Shrubbing@Home since January 5 2006 |

FX-8350, and AMD in general, always mops the floor with Intel in multithreaded tasks like BOINC. Energy consumption isn't really that different. The only real difference is that the entire computing world, including AMD, is one node behind Intel (smaller node = less energy needed). AMD does care about power consumption; if they didn't, the FX-8350 wouldn't be using the new clock gate mesh topology. Especially in Linux, AMD wipes the floor with Intel. A great example of a multithreaded benchmarking is how long it takes a certain CPU to compile the Linux kernel.
----------------------------------------http://openbenchmarking.org/embed.php?i=12102...5&sha=96eefe6&p=2 i7 3770k = 86.67 seconds FX-8350 = 82.27 seconds x264 is a great example of a multithreaded scenario using all the latest instruction sets for these modern day CPUs to speed up encoding time. http://openbenchmarking.org/embed.php?i=12102...5&sha=6dc05fb&p=2 i7 3770k = 151.85 frames per second FX-8350 = 155.39 frames per second Then comes price. i7 3770k = $290 on Amazon FX-8350 = $190 on Amazon Since all FX processors are unlocked, you can also just buy a FX 8320 and clock it to FX 8350 speeds for $165. AMD wins out here as well. This isn't even counting the higher prices of Intel motherboards compared to AMD motherboards. Factor that in, and we have a $200 difference between the i7 3770k machine and the FX 8350 machine. Is that really worth it? [Edit 5 times, last edit by mmstick at Apr 15, 2013 7:57:08 AM] |

You could wait for a few weeks and get a 4770k. Wait a few weeks longer if you use USB3 superspeed pendrives.

Cheers The energy consumption depends on both, as you can se here  the difference is only 10% while running Metro 2033. |

Tank you all for your input.
