This is probably a simple, yet common question. I'm thinking of upgrading to an i7 and adding quite a bit of ram to the set up. I've never ran anything on a 64 bit processor, so I of course have my worries. On most searches I've ran, the majority of results were articles from 2005-2006. Of course, those weren't very helpful considering how much the computer world has changed. My question is, what are the differences? Will most of my programs still work, or will I have to search for 64 bit programs the majority of my time? Here's some programs I am really concerned about: Adobe Photoshop Adobe Premiere SMartFTP (they offer a 64 bit version. At least I think so.) ConvertXtoDVD 3D Studio Max Lightwave 3D Cinema 4D Dreamweaver Frontpage I'm sure there are many others, but these are the only I can think of atm. 64-bit programs are harder to find, in my opinion. I'm just concerned if I had a 64 bit set up, if it would run those programs that only offer 32 bit. What else could I expect with a 64 bit processor? Is there anything I should know?
