SSD (on Mac) better for?

[mcurto]

This is actually a multiple question post.

My aim is to try and cut down some time on Photoshop, mainly when using big files (over 2 or 3Gb) not only when reading and saving but most importantly applying adjustments or modifying image.

I know on Mac's its a pain in the back to move the system swap files to another disk (although theres an app that supposedly does that for you (Xupport).

I just find it hard to find out what best use I could make for a SSD I would add to my existing configuration that could speed up Photoshop on Mac:

1. Install system and apps?
2. Use system swap and leave system+apps in other HDD?
3. Use for Photoshop scratch disk?
4. Any of the above in same SSD?

Other pertinent data:

Every project once completed is moved to a backup USB disk so the durability/reliability of SSD isnt really a problem.

Mac Pro dual quad-core 2.8
8Gb DDR2 Ram (soon to be 12Gb)
1 SATA 320Gb for data in use + system +apps
1 SATA 500gb for general purpose data and backups before going to external HDD plus Photoshop scratch disk

Ty in advance for any help.

You'd probably get the largest gain by using the SSD as the Photoshop scratch disk. I have an SSD as the boot drive in my desktop, and I use it for the photoshop scratch disk as well and it makes a noticeable difference.
