I'm thinking of buying a new 64 bit cpu that also includes the 64 bit version of Windows Vista.

I was told that there is no problem with having a 64 bit cpu and using 32 bit programs as long as the Windows Vista is only 32 bit.

But, if I have the 64 bit Windows Vista I could have serious problems running 32 bit programs.

Is that correct?

I converted to 64 bit a few months back. Luckily there were 64 bit drivers for my color laser printer - but, there weren't any for my TV Card, so I can't use it.

Drivers work outside of the 32 bit emulation that 64 bit Windows provides - so you can't use 32 bit drivers with it. But I've been able to use all of my 32 bit programs without any difficulties. The biggest issue that I have is one of "headspace and timing" - that is, accidentally clicking the 32 bit download for a program when I actually want the 64 bit (Windows Debugging Tools and Microsoft Virtual PC 2007 in particular). I installed the 32 bit versions and wondered why I was having problems. (no duh!)

Other than that, I'm very happy with 64 bit computing and am looking forward to increased support from manufacturer's for it. The rumor is that the next version of Windows will be the last that offers 32 bit support.
