Hi all, I'm getting the new MBP tomorrow, and I was wondering if I should get 32-bit or 64-bit Vista for it (which I need for gaming/web development). I'm getting the OEM version of Vista Ultimate. I'll definitely be using Parallels, and I know the previous version of Parallels didn't support 64-bit OSes. But does 3.0 support 64-bit? The Parallels FAQ page says it does not; however, the FAQ's also say it doesn't support 3D graphics acceleration, which 3.0 does, so I assume the FAQ's are somewhat outdated. So does anyone know if the new version supports 64-bit? And if not, how soon do you think they will come out with a 64-bit-supporting version of Parallels (i.e., is it worth getting x64 Vista and waiting to get Parallels until they support it)? Also, I just don't completely understand the pros and cons of using 64-bit vs. 32-bit. In fact, I don't even know what those numbers are referring to. Could someone explain the advantages and disadvantages of getting the 64-bit version? I've heard there's somewhat of a performance hit when running 32-bit programs on a 64-bit OS (I can imagine that would be multiplied when gaming, which I will be doing). Is that true? On the other hand, would there be a performance hit running 32-bit Vista on a 64-bit MBP? Tons of questions, I know. But I'm not very familiar with all this stuff. Any help is greatly appreciated. Thanks!
