Thinking to migrate to Vista X64(64 bit system) from XP 32 bit

They run on top of the wow subsystem which takes care of converting the api 32 calls to api 64 calls. Nothing more, nothing less. So the impact on performance is very mild, its nothing like running the application on a virtual machine or having it emulated....

Read my post again. You are somewhat wrong. There must be a 'sandbox' because most 32-bit apps must be protected from additional memory available to the system or they will crash. Read up on it.

In a way - your both right. Wowexec changes the calls and does protect memory allocation - in essence it IS emulation - but only on a very small scale. 32 bit OS's do the same for 16 bit apps. No big deal.

The key here is you get more thru 64 bit than just "extra addressable memory".

Again, you are you are both mildly right, except you don't get much more than just more addressable memory from a hybrid CPU.

Performance increases are non-existent and performance decreases are the norm, though as pointed out, it is a mild decrease that is probably not noticeable.

Darn Vista 64 bit costs more than 400 bucks.

I'm better off migrating to XP 64 bit instead.

Be aware that XP 64 is even less supported than Vista 64.
At least with consumer level hardware.

Hmm it's much more affordable.

I suspect Microsoft developed XP 64 bit as a sort of test bed for Vista 64 bit. That explains the lack of support. But so far I've been able to find drivers for XP 64 bit just fine.

And whatever runs on Vista 64 bit seems to be running in XP 64 bit as well.

Thanks for the warning. The reviews so far have been good even better than Vista 64 bit.

Running my new rig, which consists of Intel quad core 2.88, 4 gigs of 1066mhz RAM(thinking of bumping that up tp 8 gig:hmm: ), Nvidia Geforce 9800GT 1 gig, and Vista home premium 64bit.

Couldn't be happier at this stage. Running everything maxxed out, and had no hiccups yet, with the exception of starforce.

However, other threads have indicated that Ubi are sending later/updated .exe files to those who ask, which effectively patch it to "no-CD".

Awesome news, if it's true.

Personally, I would wait for Windows 7. Just as XP 64 looked to be a stepping stone to Vista 64,Vista 64 was the stepping stone to Windows 7. I did read that on or after July 1 of this year, MS will offer a free upgrade to Windows 7 for those that purchased Vista 64. In your spare time, snoop around on the net and see what people are saying about Windows 7.
