Installation of new ws, what to select XP Pro x32 or XP Pro

Dear all,

As i am going to set up a new ws for the 3dsmax 7,8, and 9 versions (primarily 9 ) i have read a lot about what to use of hardware and software OS platform. However i am confused and absolutely unsure what to select with regard to OS platform. The more i read, the more unsure i get.

I have already put together the hardware, and it is based upon an AMD CPU platform with NVidia screencard + asus mainboard \motherboard.

Main goal : best possible rendering speed.
Second goal : stability and hassle free run\operation. (i.e.drivers, viewport use, compatibility issues)

I first though is was an easy choice, the x64 had to be the gived choice here, but after some reading i am completely unsure if that really is a fact.

What to select and install? XP Pro x32 or XP Pro x64 ??

Any advice would be highly appreceiated.
Sincerely, thj.

Depends entirely on the CPU, most dual cores and higher are now 64bit and therefor a 64bit OS allows for full potential of the CPU. However, in some cases 64bit is deemed to be less stable than 32bit and can sometimes cause crashes or problems withs apps or drivers.

Personally i think its a load of bollocks because i run 64bit vista (the worst) and its perfectly fine.
