I have to add my 2 cents.. I recently made the switch to 64 bit Os and Sonar 64, I am one to tell it how it is ,no sugar coating here..
Windows 7 is new to me. had it for 2 years but just installed it 2 months ago, I must say the windows are sleek looking and thats about it for me as far as what I like about windows 7 beside some of technical aspects/improvements under the hood..
:The Good
:I see a slight improvement in overall performance / responsiveness
:Cleaner looking ( W7 ) over my Windows Xp
:More Ram Usage if needed, ( I agree with John why freeze when you dont need to) , to freeze and unfreeze makes me **** the bucket, Freezing and unfreezing is a big command and I have had several crashes related to freezing in the past. So I Tend to say away from freezing plus when I edit I dont wanna stop the transport to unfreeze to edit/ arrange ,Thats a Pita.
:The Bad
: Stuck Notes/and other related issues just in 64 bit. ( Fixs on the hopefully)
: 32 bit plugins are a toss up.
:Bit bridge if it dosn't work you forced to buy a 3rd party App <--- Pretty Pathetic (jbridge) something I will never buy Cause Cw should of either built a superior bridging Software that works with everything or licensed it from Jbridge just as they did with the Izotope algorithms. Cheap skates >>
Final thoughts:
Its here its installed it works as good or better than 32 bit in most cases. And If your willing to start over with a new install and dont mind losing some older plugins why not.. 64 bit wont be here for ever 128 is on the horizon ..its just like VST3 and USB 3.0 gotta move on with the times sooner or later.
I could never go back to 32 bit/ Xp . Its like going to xp from windows work group 3.1. then back noooo..
But I will say Bub makes a very good point.. There mostly all marketing Bull behind 64 bit. By no means will it make your productions better. But just like buying x1 or any other toy your inspiration gets a renewal.
**I will add this the best upgrade you can do that I see a major difference is going to an SSD.**
