64 Bit CPU

Hello I thinking about building a new computer for a family member and had question about using a 64 Bit CPU. Well should I go with a 64 bit or 32 bit processor? Is the the 64 bit technology popular enough now that most any application will support 64 bit?

I would go with the 64 bit. Yes it is mainstream enough now that apps arent near the problem they use to be.

Well even in the early days of 64-bit CPU architecture, you could still use a 64-bit processor and install a 32-bit operating system.

But if you are building a modern computer this is not even a real question, because they don't even make desktop processors without 64-bit support anymore.

As far as driver support/etc, there are still a few issues that are few and far between. Overall the support is absolutely there and almost everything you try on a 64-bit OS will work fine. I highly recommend a 64-bit operating system because as time goes on, less than 4 GB of memory just is not enough.

I run 64b - no probs.

every modern processor is 64-bit compatible, and you'll only need 64-bit if you plan on using more then 4gb or ram

Thanks for the replies. I figured 64 bit was the standard now, I just wanted to make sure before I got one that I wouldnt have much problem with the drivers and all.

I meant I run the 64-bit version of Windows. I have had a few problems with QuickBooks but other than that no other problems.

Its pretty much needed now, someone mentioned the ram already

..and you'll only need 64-bit if you plan on using more then 4gb or ram

This is a common misconception about 64bit processors. Memory-mapped files are starting to become a problem in old 32-bit architectures as files of over 4 GB file become more common, mainly due to large HD video files. You will notice an increase in performance with software like encoders, decoders (VLC, FFMPeg, etc) and encryption software.
