What I mean is that the limit or ceiling is so high, that today's technology would never have the capacity to exceed the limits of a 64bit OS. So yes you could install much more then 4GB of memory.
- I'm not sure what you mean when you say that with a 64bit system I "will not be able to reach the limit" ... do you mean that I will be able to use all the 4gb RAM and that there would be room for more?
Very soon, it should be here within 2 months. I'd say sooner rather then later.
- Also, can you tell me when SP1 is going to be available for Vista?
