Unfortunately you can't be generic about the HT gain, or lack of it; % gain varies considerably between different CPU's, over several generations. The original HT processors were poor compared to the most recent (Sandy Bridge). In between came the i7-900 and i7-800 series CPU's (and a few others). The last SB I bought was an i7-2600 and it cost about £150. Well worth it, especially as it consumes around 65W, slightly over half of my i7-920 @ 3GHz, but the SB does more work, making it about twice as power efficient per performance. Agreed. Plus you can overclock a 2600k to crunch more WUs and still use less power than an X6.

Listen, it is not my intention to start or continue an argument here. I'm merely trying to give accurate information to the OP.
----------------------------------------If you wish to further discuss the benefits of hyperthreading, might I suggest the most recent thread on that topic: http://www.worldcommunitygrid.org/forums/wcg/viewthread_thread,31285 No matter what your percentage gain belief is, you would need to gain 50% or more for four cores to output more than six. Both systems have their advantages and disadvantages. I merely put the information out there so the OP can make an informed decision.  Distributed computing volunteer since September 27, 2000 |

Thanks for the replies all, very interesting information. At the end of the day I want to get as many boxes folding 24/7 as I can and fold for a cure!
I was wondering if any of the official WCG projects use the GPU at all? Should I get integrated video or get a proper GPU card? |

Currently no WCG projects that I am aware of take advantage of GPU computing. There are, however, other projects outside of WCG which also run on the BOINC platform that do utilize GPU.

Seroph4x,
We for a large part dock for cures here rather than fold, the only science I'm aware doing that at WCG being the HPF2 science, but we understand what you're saying. The upcoming project to launch and the one after are also in the docking family :D --//-- |

whats docking mean? i thought folding meant the same as crunching numbers and running WCG for a cure

In layman's terms, docking is akin to fitting a key into a lock. The scientists are looking for molecules which will "fit" into a disease(target) molecule and are able to penetrate the membrane of the target molecule kind of like a key into a keyway. Both the target and the molecule under study are manipulated in three dimensions to see how well they might fit into each other. If they find one, then they need to determine if it will make a good drug. For instance it does no good to find a molecule which will kill or disable the disease but is also toxic to the host or has bad side effects. By computer screening many molecules it helps to narrow the field for the experimentalists to do the lab work by only having to deal with perhaps a thousand molecules out of a field of millions or billions. It also helps them by identifying some candidates which may be close to what they want so they can work to synthesize something better based on the close ones.
----------------------------------------Folding involves how proteins collapse or fold in on themselves to find their final structure. The mechanism of how and why proteins fold the way they do is very complex, with only slight differences in the atomic makeup of the protein resulting in a different fold or collapsed state. The protein may only be effective if they are folded a particular way. Folded differently may make them toxic, neutral or have other unforeseen consequences. I am not a computational molecular biologist but I hope I am pretty close to the mark. If anyone more learned wishes to chime in, be my guest. i am always willing to learn more. Cheers
