What is the difference between 32-bit and 64-bit and which should I choose?
Well, I've recently bought an Alienware M17X and it has and Intel processor, which I've never had before. My last computer had an AMD processor,which ran only Ubuntu 64 Bit. I had installed Ubuntu 32 Bit first, but I had lots of problems, and one of them was the machine temperature, that gets lot hotter when running a 32 Bit version. My new processor is an Intel 7320QM and it runs Windows 7 64 Bit fine. But like my older machine used to run Windows Vista 32 Bit fine, but not Ubuntu 32 Bit. It doesn't make sense at all. So I need to know if one of you guys have ever experienced something like this befor? Which version should I get for my Intel processor, 32 or 64 Bit?
