Do yourself a favor and size your SSD MUCH larger.  As Curt has mentioned, making a RAID array out of several SSD drives will really kick up performance (I have four SATA3 SSD drives in a RAID 0 as my system drive C:, for a total of 2TB of space - it screams).  Traditional advice is to have a physically separate HDD for use by Photoshop for scratch, but with a RAID 0 arrangement and a lot of extra space you get advantages from running everything off the system drive and achieve extremely fast, fluid performance in everything you do.  It's really the way to kick a modern system up to the next level of performance.  Lastly, you should know that a number of folks have come on this forum complaining of problems running Photoshop in "non-standard" setups, where they have done special things like relocate their Users data area off their too-small SSD drives.

Get even more RAM if you can, especially if you're going to get into making panos.  Photoshop uses a lot of RAM for these operations.

You haven't mentioned what Adobe apps you're considering using, but for just Photoshop my own opinion is that ATI video cards are a bit better.  As an OpenGL software developer, I find the AMD/ATI display drivers are of higher quality than nVidia's.

Also, I don't see mention of a monitor.  Do you have a good one?  If you want predictable results, especially if you send your images out for print, you might want to consider a high-end monitor, and a calibrator/profiler to go with it.

I don't know whether you're interested in a "non-standard" approach, but I have had good luck buying off-lease workstations from eBay.  You can get just-off-cutting-edge technology that's quite powerful sometimes for a very good price.  A high-end multi-processor system from a couple of years ago can still sometimes outperform today's builds for a lower price.  If you're interested in investigating this I can make some suggestions.

Best of luck, and most of all have fun!
