Re: upgrade to 16GB....no gain in speed?

wow, 32GB....I read from Chris's reply it will benefit from changing cs4 to cs5 or 6.
Since my internal disk is pretty full and thi is the one I use for scratch, would choosing an external hd as a scratchdisk be an improvement or would the USBinterface slow it down?

If you have enough RAM, Photoshop will not write any data into scratch.
I would recommend to use an external disk as scratch in your current configuration (leave all as is and set scratch to an external disk).
Then after several hours have a look at your scratch disk command+I:
Then you will see how much space Photoshop took.

The change to CS5 and CS6 should really bring benefits.
There is a good place to get information that you might already know:

And here is a very useful link too:

you can see a memory status indicator right within your dock (in Lion).

Re: upgrade to 16GB....no gain in speed?

Photoshop needs a lot of Scratch disk still....it doesn't matter how much ram you have. And the disk still needs to be left alone by itself. The fastest connection allowable is desirable of course. You might read that tests have been done that show that PS doesn't NEED scratch disks...but thats nonsense. There are still processes that use scratch disk a lot.

Yes, install lion as an external startup utilizing USB 2 at least or FW 800. If you have thunderbolt even better.

If you go to your info palette and in its options to show scratch usage you will see as soon as an image is opened that PS allocate scratch space. The longer you keep PS open the more ram it "keeps" and the more it depends on scratch space.

I agree with Chris. If you have an express card slot you can connect your external drive via eSata.

I found this older thread:

http://www.retouchpro.com/forums/har...cbook-pro.html

I ordered my RAM and eSata express card from OWC and I must admit that I was very happy with their service. This card is even bootable and you can install second system on an external hard drive.

Great advice on the external drive boot option, very easy and painless on a Mac. Great way to experiment without harming your main system. In fact, I have Lion installed on an external bare hard drive for access should I need it (I haven't switched to Lion yet for everyday use because it breaks a couple of older apps I need).

As for the video card upgrade, unless one has a Mac Pro, switching it out is impossible (without a trip to an Apple certified repair shop). The G5 iMac was the last model users could pop the back off of. (And good thing, that way you could check and see if the notoriously bad capacitors were Jiffy-popping!).

Unfortunately, company that made this computer doesn't support professionals as they used to anymore …

Edit: How much $$$ is enough?
