Windows Vista - 32bit or 64bit?

[FRKT]

Hi there,

I'd appreciate it if anyone could offer me some advice on whether to go with the 32bit or 64bit version of Vista on a 4-core 'Nehalem' Mac Pro. I've read that some drivers will fail to work under this version of the operating system - is this the case for the hardware in the Mac Pro (particularly the HD 4870)?

How much RAM do you have?

6 GB (3x2GB).

I would install Vista 64bit.

1) No 4GB file limit
2) Maps to +6GB of RAM
3) Faster overall.

Thanks. So there are no issues with the hardware in the 'Nehalem' Mac Pro and 64-bit drivers?

I have 64bit on my MBP, drivers shouldn't be an issue. Applications might not want to run but there's a compatibility mode that usually fixes that.

... and I've already made sure there are 64-bit drivers for the ATI Radeon HD4870. Great! Thanks for your help everyone.
