Let me see
Photoshop is 32-bit, so it can't use more than 3GB of RAM; Logic can run with 2GB of RAM and just about every other Pro app can benefit from faster read/write to a scratch disk, so I still think the SSD is better.
come on alphaod your foretting that you can have more apps open at one time. your argument is fine if you only open one app at a time.
