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.
