Those upgrading from CS4 won't find it a change.Īs ever, this is a monster suite of software, and even the most experienced user will spend a lot of time digging around finding and playing with new stuff. Interface-wise, if you're coming from CS3, things are a little different – you'll be working in a minimalist cool grey GUI, though the familiar paradigms remain. Having said that, I've been running it on my older machine, which is 64bit but which only has a single-core processor and 2GB of RAM, without any issues.
There are 32bit versions in the box, but you really need 64bit to be able to address lots of RAM – and lots of RAM is key to keeping a big app like Photoshop running smoothly. The most significant change, though, is that the suite is now 64bit.
