It is time to get a new box, and that means a new Photoshop install. My trusty Dell is about 6 years old and has been showing signs of dementia - blue screens, freezing and random powering off. I am fine with getting a replacement as my file size for processing has grown with medium and large format files that exceed 400mb. I also want to reconfigure the computer using a dedicated SSD for the OS, Photoshop and LR, and out of box access/storage. I have worked with Photoshop since PS5 and currently have used CS5 for many years. I would be happy to transfer that program to my new box, but that is not possible because the CS5 I have installed was the result of various upgrades from PS5 over several years. And I understand that the program can not be transferred in whole cloth to my new processor. It appears I can get a new copy of CS5 (legit) for about $150. The subscription based service is about $120 per year. The math only works if there are significant advantages of CC over CS5, and whatever else Adobe offers for incentives. I also use LR for my preliminary processing and have access to a new version of that as a premium for a new camera I purchased. Consequently, are whatever improvements over CS5 that CC offers at present truly worth a decisive increase in cost over time with the subscription-based CC. Thanks for your thoughts.
