As an web developer I am using this software from last 9 to 10 months and I find many bugs like it hangs a lot while writing bunch lines of code.
It do not work on low processor, it take a lot of time to minimize and maximize the window.
The thing about Dreamweaver is that you can can connect our database directly in it without opening extra browser page for php my admin.
It is basically made of web developers not for starter.
It is the for front end developers because it supports HTML5, CSS3, JAVASCRIPT, COFFEE SCRIPTS AND many more. It also supports back end programming languages such as PHP but the suggests are not good for PHP.
The installation process take some time but its okay for large software.
It available for both 32 bit version and 64 bit version.
I bought it from Amazon.com for approx 240 bollars.
It consists of inbuilt templates which helps the developers a lot because it saves a lot of time.
So if you laptop or desktop having processor greater than dual core you can purchase it.
