I am using this software for very long time and I am very impressed to it because it doesnt consume much ram gives you the awesome result.
Adobe has created may photoshop version and it has many improved qualities from the previous version and it can run freely in my laptop in which I have 4 gb of ram and it doesnt lag but it little bit lags when you used some third party plugins like topaz collection, nik collection etc. Other wise the software runs smoothly.
The best feature of this version is it supports camera raw plugin which gives you to edit your raw photos and Camera raw takes your photos to the next level.
I am very satisfied with this version and I am happy by using it.
Thank you.
