32-bit vs. 64-bit systems
I am getting a custom laptop, I only do .net development, I don't play games or download gbs of video/music. I just want a fast computer. Right now in order to get 8gbs of ram I have to have the 64 bit version of 7. I need to know the following: What pitfalls could I encounter. I know a lot of apps out there are not 64 bit apps and only come in 32 bit version. Business Intelligence Development Studio is a good example.
