First of all, CS4 is 32 bit only.
Where you could potentially benefit the most from a single SSD depends very much on your total disk setup. But my feeling is that money spent on a single SSD is better used to buy 3 or 4 additional 1 TB Spinpoint F3 disks and improve your setup. For around the same amount you will get much more storage and better performance.

Reading the disk article as we speak, thanks.
Regarding CS4 being 32 bit, I recall you saying the other day that a minimum realistic system would be 12 gigs fo memory. Given the 4 gig limit in the 32 bit architecture, were you referring to CS5? Not sure how CS4 would benefit from > 4 gigs.
Chris, I was mainly speaking about CS5, but CS4, although being a 32 bit application, has been optimized to use more memory than 4 GB, so even in CS4 it pays off to have more memory.
I notice the drives you recommend are 7200 rather than 10k. When spreading i/o out over three or more drives, does the difference between the two speeds become negligable?
I think it is about bang-for-the-buck. The F3 is indeed 7200, but local prices for the 1 TB F3 are around € 58, the alternative WD CB 1 TB SATA III is € 82 and the WD Veliciraptor 600 GB is around € 250. The price difference more than justifies the marginal performance gains if there are any, and in tests the F3 is usually the fastest 7200 disk.
Kinda figured that was the case. I'm big on bang for the buck, so that's worth knowing.
