So, I know there are a few of you that mentioned owning PSCS 6 already. I'm still using 3. I have an opportunity to get 5 cheaper than the upgrade price to 6... So I do it or just wait until I can afford 6 and not worry so much about it. How HUGE or the changes from 3 to 5 vs 3 to 6?
Any opinions will be helpful. 
Thanks in advance for your help!
I would definitely upgrade to CS5. Although it's been awhile for me, and I don't remember everything about it, I seem to recall that the jump from 4 to 5 was substantial. I think that's when they added content aware and lots of other cool stuff. The jump between 5 and 6 was minimal. I would not wait until you can afford 6, it's not that much different.
CS3 was great when it came out. But going to 5 or 6 is a big jump.
There is another discussion covering the changes here, take a look at it.
Going to 5 you will see the content aware, red eye reduction, plus a lot more.
Going to 6 the content aware was reworked, as well as the crop tool, plus the following:
Here is a list of some of the new features:
UI redesign
Auto and background saves
Content-aware Patch and Move tools
Blur Gallery
Color Range: skin tone and face detection
ACR 7
Crop tool
Properties panel
Video support
Oil Paint filter
Auto correction settings
Adaptive Wide Angle filter
Type Styles
Printing UI
JDIs

Thanks Ladies! I just didn't know if it was worth it... but sounds like some things have been made easier even though it may throw me for a big learning curve going up to either.
PS @ Judy: the other discussion here wasn't linked.... just in case someone later down the road reads this thread and can't find the exact post you are referring to.
