No your expecting to much. I dont care how much RAM your system has, what CPU you have or anything like that. you will not see any system out there that you can push the power button and be at your desktop before your finger is removed from the button.
your expectations are what is wrong. Photoshop is a VERY intensive program. No matter what system you have running it takes time to load. It takes up to a minute cause of all the junk it has to load. No system, no amount of RAM will help. even a SSD will not help.
