Well according to that link thecYrus posted, the 64 version makes no difference

Nice new technology.

Errr, Vista makes a difference if you actually get the 64-bit Vista. Obviously with the 32-bit Vista it won't make any difference.

There's also a Windows XP x64 but if you want to go the x64 route then I actually would recommend Vista, because the XP x64 was kind of a half-baked update to a product release 5 years before, while 64-bit support has been integrated into Vista right from the start.

Vendor and driver support still kind of sucks for x64 though.

Yes Digi, thats what i though.

But how much increase in performance can we expect when going strictly 64 bit?

Assuming you had a 64-bit OS, with 64-bit drivers for all hardware, and applications compiled for x64 and designed to take proper advantage of it, you could probably expect a 30-40% performance boost.

Without application support, but with driver support, maybe 20% tops unless it's a really graphics-intensive application or something.

Without driver support... not much.

One other thing to keep in mind is that a 32-bit architecture limits you to 4 GB of address space (practically less than 3 GB of available RAM most of the time), and this can't be overcome without complicated and gross hacks like PAE. We're pushing the 4 GB mark already as most people have 2 GB now, so that will be an issue soon, solved on 64-bit OSes.

xp sp2 supports 4gb right?

my friend has vista. i just utterly hate it. xp the way to go everyone. just the interface itself makes me sick. it doesn't really look user friendly, not as much as xp. either it sucks or it could be that i hate changing from one operating system to another.

This is true, however you have to understand what that truly means to the Windows OS.

Memory in Windows is split up in whats called 2 "modes". There is kernel mode and there is user mode. Both these modes run at the same time. Kernel mode is where all the code that communicates with the hardware resides, and user mode is where all the code that you use (read, applications) resides. One of the reasons for this is so that if there is a hardware failure, there is less chance of that failure taking down the whole system, and Windows can recover gracefully instead of the old BSOD that used to haunt us during the 95/98 days.

The 64 bit OS will increase the amount of memory addressable in these modes. Traditionally, Windows is set up to use 2GB of memory in kernel mode and 2GB in user mode, so one application can only address a maximum of 2GB of memory at any one time. It is possible to change this to use 3GB in user mode and 1GB in kernel mode using the BOOT.INI trick, but this is not recommended, especially for a DAW as it can compromise the speed in which Windows can communicate with the hardware.

Further to that, the 4 GB is 4 GB of address space. That is not the same thing as memory. Are you running a video card with 512 MB of video memory? Well, that needs to be addressable on a user-mode display driver so now you only have 3.5 GB of address space left for memory.

It's not just video cards, of course - there are several devices in your system that take up address space. Some of them may reside in the kernel address space but many do not. In practice you're not likely to see more than 3 GB of addressable physical memory on Windows XP without PAE.

64-bit Windows extends the user-mode address space to 8 TB. Should be plenty enough for a decade or so. Of course, applications still need to be compiled with the appropriate switches to be able to address that much better - if they're not, they're stuck with the same old 4 GB.

I was playing around with Vista at Best Buy. To me it was a hole step up in looks and user compatibility.

I think currently there is only 1 native 64-bit DAW app. Sonar Producer edition. But even then it has some "Bit-Bridge" technology that handles conversion of 32 bit vst's (all of them).

I guess once you get the midi to audio you would notice a definite improvement. Plus all the Midi and Audio effect are Native 64-bit in Sonar 64-bit edition!

A good read here!!! The State of 64-Bit Computing in the Music Products Industry
