...and what a difference!
I know others were running dual cores here, so I knew my OPUS would be up to the task.
I didn't hold out for the (much) more expensive 2MB L2 cache version, because the benefits aren't really worth it on such a narrow-focus PC.
BTW, I had a 1.8Mhz single core before...which held it's own fine, but it's just SO much snappier now using the PC, especially with the DSP running in the background...
Yep, I'd recommend a dual core of any speed... they are as you said, just SO much snappier... even just a 3600 dual core.
While a car-pc doesn't need anything special, a dual core on its own (nothing fancy, look at mine :P) will make a car-pc a lot easier to use. Lots more processing power means less waiting and less likely to have songs stall.
My old AMD 2800+ (single core) was a bit too slow for a car-pc, ran centrafuse fine until something in the background happend then everything will slow down... and also when searching through music was a bit slow... and sometimes (rarely) stall'ed while playing songs!!
I did some testing, and I can (barely) run my audio stream at 24-bit, 192Khz sampling with the dual with AudioMulch doing all the DSP...
However, the best material I have us 24-bit, 96Khz (DVD-A, SACD), and it handles it like a champ at that setting. Maybe not a totally audible difference (by ear), but like they say, your chain is only as good as it's weakest link!
