A discussion of overclocking belongs elsewhere in the main, but I
suspect I am not alone in having a working SD system but wanting to
look into HD for the future.
In that regard a discussion of CPUs is relevant, and I just wanted to
point out that the Opteron series is often overlooked because they
are "server" chips (whatever that means).
The results posted here by many folks about success or failure to
playback HD well seem very inconsistent, I suspect because there are
so many unreported variables such as what else is running, what
window manager/desktop, what resolution, what if any de-interlacing,
and many other factors.
But a lot of folks seem to *almost* be able to playback HD, and for
them a mild OC (perhaps 10%) might make the difference between
working well and not.
