A lot depends on the video card used. A VDPAU capable NVidia card
will hardly put any load on the CPU when viewing a video.<br>
So if your system is capable to function as a backend, plug in a
VDPAU capable video card and you can use it as a frontend too.<br>

<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>
