Pretty hot, personally I'd prefer the AMD Phenom II, but that'll wait until Christmas. Ye old local Chinese clone store, the guys that made the video server.
The only problem you've going to have with a 192mhz sample rate is the digital input you are using, Most equipment won't accept anythng faster than 48 - 96 mhz in the digital optical input. Just for kicks I am figuring that to get the best use out of this multimedia I/O box you're going from pin plug to a transducer to optical -> receiver. I know my Yamaha turns into a straight pipe at speeds above 48mhz, and this is not a really well documented spec, you only know it after you do it. I use a Creative card so I use the creative software to insure digital output only, then I use the SRS virtual device for a little more punch. I run 24 bit at 48mhz, the card will let me run faster, but the destination port won't accept a faster sampling rate, it
Should you use regular output cabling, you are stuck with this limit, and whatever transduver you use will have to go from pin plug to phono plug. There are more elegant soulutions but they are far more costly.
When I bought my present hunk of chips, she was one of the first dual core machine that also supported PCI-E standards. Ths December she'll retire to the server farm, 2 years and $1500 later. I added both the soundcard and the graphics card, the software that came with the onboard was ok.
Enjoy the process, me I hate to assemble, this was my first Dell, maybe my last, I'd rather have the guys at the local clone store do my assembly, they have just the AMD Phenom II I have been looking for. Then comes the customization. My biggest decision is will my current machine turn into a Linux machine when she goes into the farm.
