In case anybody is following this thread: I totally agree that Photoshop does not require a 64-bit OS. It worked well on my old machine with XP. Photoshop definitely works faster on Windows 7 Pro 64-bit, however. A casual Photoshop user might not see much difference, so 32-bit would be just fine. When working on multiple large files at the same time, the 64-bit is faster and helps with the work flow IMO. There are some studies that say up to 15 times faster. Even the 64-bit can bog down when things get enormous, though. Nothing’s perfect…
