THANKS SO MUCH, everyone---very helpful! I have looked at the specs on my current computer and wonder if I am getting ahead of myself. It is a 5-year-old Dell XPS 15: - disk drive: LITEONIT LCS-512M65 2.5 7mm 512GB (it doesn't say SSD but I believe it is) - processor: i7 3632 QM CPU@2.20 Ghz (8 of these) - 16 GB of RAM - two things are listed under Display Adapters: intel HD Graphics 4000 and NVIDIA GeForce GT 640M (Does this mean I have dual graphics?) The biggest problem I have with this computer is that, for instance, today it has only 303MB of free space. I do own 2 external drives, one is 1TB and the other is 2TB. I am willing to transfer most of my photos to these drives provided they are backed up somewhere--my photos are precious. At the moment I have Carbonite backing up my computer and the 2 external drives backing up each other. Obviously I need to move more files off the computer ASAP. I also own a Wacom Intuos tablet (a gift) which I have never learned to use. A friend of mine, also a Photoshop junkie, has a large high-end display hooked up to her laptop and loves it. The other major problem with my current computer is that the fan quit a long time ago. I have it raised up about an inch above my desk surface with a tiny electric fan blowing underneath it. Shabby but does the job. Looking to the future...I won't be doing animation but I have dabbled a little in editing my own videos (cropping and combining with still images and music in slideshows) and enjoy it. What has prompted me to get a new computer now is that I have just begun a new project that I believe will stretch my computer, Photoshop, and my own abilities to the limit...a Photo Mosaic to hang in my home that will be 8' x 4' and contain about 300-400 of my photos. I am interested to know what you all think of my current computer and if an upgrade is a good idea. I am very willing to spend some serious $$$ on a new system if it would make a difference. THANKS AGAIN for your help...
