Thanks, I was leaning towards the 32-bit (x86) Version but just couldnt make up my mind.Go with 32-bit.
Most games are designed for 32-bit and may have problems on 64-bit platform. Also you may have driver issues with the 64-bit version of Vista. From what I've read, it seems you should only go with 64-bit if you have specific applications that can use a 64-bit OS. Otherwise it's not worth the potential headaches.
Sorry for the late reply, but: The opposite of what you say is equally true.Most games are designed for 32-bit and may have problems on 64-bit platform.
That is the word on the street, however in order for a driver to get WHQL certified, it HAS to support the x64 version of Vista. Drivers are currently an issue for 32-bit as well (although it makes little sense as OEMs have had a LONG time to prepare and the changes AFAIK aren't that big, except for the video drivers).The x64 version is technically faster but the x32 version is more compatible with everything, including games and hardware.
