  <p>People are recommending 64 bit, can you explain why? Is it just so you can have more then 3GB of addressable RAM that 32 bit gives you?</p>
  
  <p>And how does Visual Studio benefit from all this extra RAM?</p>
  
  <p>I went from 64 bit XP back to 32 bit due to 90% of the software I was using only being 32 bit anyway and I had issues with drivers and some software with 64 bit.</p>
