how big are these photos that you are looking at? boot times, I don't understand why people put such a big emphasis on this, even with fast SSD's, you're only shaving a few seconds off in most cases. Program load times would be faster but again, unless you're loading up a monster program, we're talking like 1-2 seconds difference from 5400rpm drives in most cases. Depends on the 500GB drive you are thinking of. The best buy for 7200rpm drive at this time is the Seagate 7200.3 320GB. It's around $94 CAN. I don't know where you are located so I can't give you locale-specific pricing.
