Firstly, let me declare my ignorance in x64 systems. I have read a bit but plz do not be surprised or irritated
I need to replace my old Pentium-not-even-CoreDuo notebook. I have a bargain to get a brand new Intel i5,64bit architecture notebook running Windows 7 64bit at almost half the price. The thing is I know nothing about 64bit. The important info I got was that incompatible Antivirus programs may have issues running ontop of x64 OS's and the most important advantage is the amount of memory that can be allocated in an x64 system.
As we all know its always better getting info from your colleagues who can share invaluable experience and advice... its not that I'm lazy to search for info.
It got me thinking about all applications that I would like to run, from graphics to programming. Do I need 64bit versions of all the software? As I also program in C++ and sometimes Java, will my output be specific to x64 architectures? What about my Dreamweaver and Photoshop? And will I run into the headache of looking for x64 applications?
I've read about WoW64 but I still value your experiences and advice.
