I am in the same situation - digital image and video editing.
Is your motherboard SATA III (6 Gb/s) capable?
Based on all of the reviews and comments I read the past couple of months, especially about Adobe products, I would say the Intel 510 series would be a good choice. If price is an issue, then consider the Crucial C300 ssd's. You might be able to get one on sale.
It is. I'm def goin with the C300s those look sick.
