I am using a 2009 MAc Pro with Photoshop CC 2017, and am considering upgrading my machine with an SSD , a new video card with #gb of RAM, and adding RAm to total 32 GB from the folks at OWC.
My current config uses a dedicated, 10,000rpm hard drive as a scratch disc.
If i upgraded my machine with the above, do I even need a dedicated scratch, or is the added Ram enough to give better performance?

I think this was answered in another spot on the forum. Anyway, what size SSD are you contemplating? If it's adequately sized I don't think there's a need for a dedicated rotational scratch disk.

I am considering a 1TB SSD and about 50-60% will be used--so have a lot of extra, unused space.

I'm not sure that provides lots of extra unused space. You may want to check with some SSD performance gurus and sites. Most I've read recommend keeping 50% of the SSD capacity available. Rotational media and SSD drives differ greatly on how they reclaim free space.
I'll search and see if I can find some articles that confirm this or debunk this. SSD tech seems to move quickly.

I found some forum posts on Tom's Hardware recommending not to fill an SSD beyond 80% but that it varies by SSD.

How big a file are you working with? Generally speaking, unless you're working with huge files, you'll be fine with a single SSD. The reason for a separate SSD would be for taking out the 3Gb/s limit on the SATA port. I will state that PS really is a pig on free space, so keeping a good amount of free space is critical.

You could try creating a Fusion Drive via Terminal, though I believe it would benefit a slower spinner more than it would your 10K drive. Downside is that when one of the drives dies, everything is gone. But that’s what backups are for! ;)
