pwillard,

 

Thanks for the advice, but I understand I need a Windows XP license, which I don't have. Anyway, I'll give it a try.

 

 

Peter,

 

There are a few reasons for using Vista x64.

First, all the background tasks, such as superfetch, defragmenting, automatic updates, packet decoding for the network controller, etc are handled in 64-bit mode, wich makes them a little bit faster, so fewer processor cycles are needed. This also saves me a lot of cycles when it comes to parity calculation for my RAID 5 array. My Athlon 64 X2 3800+ would easily reach 100% load under 32-bit Vista, but under Vista x64, it hardly ever does it, even when running single-threaded audio video encoding apps.

Second, I want to go 4GB in the near future, and I would not be able to do so with a 32-bit OS.

Third, I'm working on some algorythms that use 64-bit floating point math. While they are not very complex at the time, I would not want to run the calculations in 32-bit mode.

Besides that, there is no real advantage to running 64-bit Vista, and I haven't seen any noticeable performance increase or decrease for 32-bit apps compared to the 32-bit edition of Vista. I've read the article you linked, but I haven't had any of the problems described. The only problem was lack of drivers at the beginning, but that applied to the 32-bit Vista as well.

 

Thanks,

Alex G.
