custom builds

FIRST off... my apologies if I am being unsensitive or rude in my asking, but I will ask the best I know how.
 
In the above user forums, you really see A LOT of complaints, crashing, etc.  I realize bugs exist and that the posts may really only represent a small fraction of actual users.
 
My question is do the custom build computer from the great folks that post in this forum or even stepping out to a Sweetwater build WITH the software installed seem relatively glitch free for the most part?  Many,many, seem to state they'd pay for a Cakewalk update if it was totally under the hood and fixed problems, rather than add bells and whistles.  My 7.02PE is fairly stable, but is known to crash and my Ctl S is a reflex at this point.  Since my audio computer is getting a little old on this end, desiring synths like Omnisphere...  I'd be willing to spend an amount extra for the "insurance", as admittedly, the builders need to make a living too, versus a 'do it yourself'.
 
Again, I am NOT downgrading the great builders that frequent here, as I have no experience with their builds and nothing to comment on.  It seems almost 100% of the owners recommend these people, and that in itself is very impressive and probably answers my own questions.
 
Thanks

A well researched, designed, and thoroughly tested PC for DAW use will go a long way towards trouble-free performance -- which is exactly what a professional builder (such as Jim or Scott) will provide.

However, the PC itself is only part of the equation in the quest for glitch free performance. The choice of audio interface and the quality of its drivers (or lack thereof) can easily make or break a rewarding and productive DAW experience.

We're still not done. The choice and use of 3rd party plug-ins and virtual instruments can also have a profound effect on a PC's perceived performance, and there are a near infinite number of combinations.

Finally, there's the human element. We all tend to use these incredible tools in very different fashions. Some of those tendencies may support trouble free performance, and some are likely to work against it.

The bottom line is that trouble-free or glitch-free performance is something we (and the software manufacturers) all aspire to, but given the enormity of the variables involved, perfection is unrealistic -- but we'll keep trying.

Sonar users have the benefit of this forum with a wealth of experience to help us all on our quest for a rewarding and productive recording experience.

I should also point out that any good custom DAW builder can assist you and provide guidance with ALL of the above, giving you the best chance of achieving your goals.

Oh, I should add that if you are content to do a lot of research, are very computer savvy, and able to build/tweak/fix/modify your own computer, one certainly can build one's own system.  For many of us, if not most of us, that is not a viable option.
