While it might offer secondary advantages, for direct usage more RAM will make no difference for you. Photoshop CS4 for Mac is 32bit. As for secondary advantages, it might help with other apps running at the same time, including OS operations.

But I'd still recommend upgrading.

Will it help with running filters (i.e., lens blur or rendering effects in illustrator)? Those really slow down my workflow.

I doubt it will do anything directly to speed up rendering, that's CPU dependent.

Re: 8 GB ram help using Adobe CS4 ?

not really, photoshop for mac it can only handle 3 gb of ram as maximum, if you want to speed up your system i recommend to assign a dedicated hard drive as scratch disk, not a partition but a whole drive. my suggestion is to get at least 40gb drive at 10000 rpm
i hope that this little advise help you.

The scratch disk is the disk used by Photoshop to replace physical RAM. This is defined in Photoshop's preferences. To work best the program needs free space on the scratch disk equal to about 4 times your file size. ...

Now if you haven't set up an scratch disk for photoshop, that means that photoshop is using the main hard drive (System Har Drive) as a scratch disk.

now to set up a scratch disk just fallow the instructions bellow
1. open photoshop.
2. open photoshop menu and then select "Preferences".
3. under preferences clic on "Performance" submenu.
4. a new window should appear.
5. that window should have 5 sections (1.Memory Usage, 2.History And cache 3. "Scratch Disk" 4. GPU Settings and 5. Description)
6. now in the scratch disk selection it should be list of the hard drives that you currently have install in your computer, if your system drive have a check mark before its name unchecked and select another hard drive that doesn't have nothing to do with the system drive "non a partition"
7. click ok.
8 close and reopen photoshop "THAT SHOULD MAKE A BIG DIFFERENCE"

Oh i almost forgot try to reduce the history states as much as you can.
i hope that this help you

Shortly:

More RAM allows bigger pictures, more layers and more history states. It doesn't improve the Photoshop's performance.

More Processors improves the Photoshop's perfomance, not the amount of RAM.

Only getting Adobe 64-bits and Leopard (or later) 64-bits will address more RAM to each 64-bits compatible apps. Both, apps and OS must be 64-bits to work.

I have a MacPro with 2 quad-cores of 2.8 GHz and 8 GB of RAM.

Here is an snapshot I did of the use of my RAM. PS and LR opened.

Check that 8 GB is cool for this. I'm running a 32-bit OS and Apps.

For the secondary advantages. RAM is one of the cheapest ways to improve your system. Even if it doesn't speed up Photoshop, it will still help in other ways.

Re: 8 GB ram help using Adobe CS4 ?

Wow, thanks guys.. Quantum, thats really amazing. I can't believe I never heard of that before! Is it very safe to use a scratch disk? (i.e., if you save a file and it is open and your external harddrive fails..) Also, does the hd have to be completely free from other files for scratch disk use? It seems like you could just put something in your computer if its small as a 40 gb hd or something
