Should I upgrade PS CS3 & Leopard to PS CS4 & Snow Leopard?

[DHart]

As a pro photographer, I use Lightroom and Photoshop CS3 heavily every day on my year-old MacPro, iMacs, and (yes) 4 month old MacMini.

I haven't upgraded to PS4 yet, nor have I upgraded to Snow Leopard. PS3 and Leopard are serving me well and I'm not lacking anything... that I know of. Or am I?

Is there much compelling reason to bump Photoshop CS3 up to CS4?

How about moving up to Snow Leopard as regards compatibility with Photoshop CS3 or CS4?

I've been taking a wait & see attitude on these upgrades, and wondering if upgrading either PS or the OS will present any problems which might make me wish I hadn't upgraded.

Thanks for the advice.

I'm using Snow Leopard with CS3. I just didn't see the point of spending the money to upgrade to CS4. It's not 64-bit. It's not even a Cocoa app.

I guess CS5 may not be too far off. Is it likely to be 64-bit then?

Perhaps I'll upgrade to Snow Leopard now and keep using CS3 until CS5 rolls out. Any issues running CS3 on Snow Leopard?
