<div><div><div style="font-size: 12pt; font-family: times new roman,new york,times,serif;"><div>I would like to build an Ubuntu box that will serve as a back end for Myth, and I **MAY** make it a front end at some point as well. If it ends up serving as a FE, it will get a discrete nVidia GPU. Size and noise is not a concern with this box, as it will sit in another room from the TV. Here is what I would like to do with this box:</div>
<div><br></div><div>1). MythTV backend.</div><div>2). Commercial flagging.<br></div><div>3). Mythweb server.</div><div>4). Run sshd so I can get in from
work.</div><div>5). Syslog server for DD-WRT router logs.</div><div>6). Transmission bittorrent server.</div><div>7). Storage for media such as photos and music. Music will be accessed by a Windows PC with iTunes for synchronization with iPhone.</div>
<div><br></div><div>For MythTV, I have an HDHomeRun Prime (3 tuners), which I believe
sends MPEG2 directly to Myth, so there is no encoding that Myth needs to do with this if I am correct. All content is HD, and I do routinely record HD with all three tuners at once. While recording is taking place, I may be viewing HD recordings on up to 2 frontends at once. Live TV is not used at this point, and I do not anticipate needing it. </div>
<div><br></div><div>The processors I'm considering are either a Core i5-2405S Sandy Bridge 2.5GHz (3.3GHz Turbo Boost) LGA 1155 65W or a Core i7-2600S Sandy Bridge 2.8GHz (3.8GHz Turbo Boost) LGA 1155 65W, and there is about a $90 price difference between these two processors. <br>
</div><div><br></div><div>So my question is, will the i5 handle these tasks with a little room to spare, or do I need the i7? I don't want to pay for CPU that won't get used, but I don't want to come up short, either. <br>
</div><div><br></div><div>Thanks in advance for any
advice!</div><div><br></div><div>--John<br></div></div></div></div></div></div></div></div></blockquote></div></div></blockquote><br><div>I too run a Core 2 Quad Q6600 2.4ghz as my backend and sometimes frontend ( used to be full time frontend / backend ). </div><div><br></div><div>I run two dvbs tuners with 3 virtuals each and can record multiple hd channels and watch back something at the same time with no issue. </div><div><br></div><div>My backend also runs myth web, MySQL, mail server, file server one virtual box windows vm and serves as a desktop for light web browsing and email duties. <span class="yiv726302732Apple-style-span" style="">I also run motion ( similar to zoneminder ) with 4 cameras.

sounds like the closest comparison to my use case, maybe even more intensive with boinc. This is great news, as I will save some cash going with the i5, and probably put that toward more storage. Now the next step is to choose a motherboard. Are there any chipsets that are preferred or chipsets to be avoided? I will need good PCI support for the CCTV capture card for Zoneminder, good SATA throughput, and an audio chipset that works will with Linux and Myth.<br><br>--John<br><br> </div> </div> </div></body></html>
