All of this stuff is way overblown and way over hyped imo. It is the same old argument that floats about over Protools -v- just about any other DAW -
"well the experts and pros all use it so it should be the best, right?" well, no wrong...as many users of Sonar (including the OP

) would attest to. The same with the hyperbole surrounding all these "tweaks" I mean really, fans for each HDD, you are kidding right? How ridiculous. A solid well spec'd off the shelf unit with later versions of Windows (7, 8
.1 or 10) and you are pretty good to go.
Really, I think a lot of this stuff is possibly put out there and maintained so companies like these can stay in business, if the truth were known they would be far less profitable. An analogy could be drawn to Anti Virus programs in the late eighties and into the nineties - putting out less than accurate information to a gullible public to sell more product.
And I guess now we will get all the "anecdotal" evidence, and test-bench contrived evidence (that actually means diddly-squat in the REAL world) to "prove" that you need a PC specifically tweaked to do the job....well one piece of anecdotal "evidence" I can provide is I have been using high street boxes for years, and running everything (games, internet, movie watching etc etc) as well as intense audio work (with Sonar btw

) with NO issues that were not user error.
My advice? Take all of this with a grain ( a BIG grain) of salt! Rely on your own experiences and as always JMO!
