thanks for this but i solved it better. Bought an imac. Different set of problems but not performance :-)

You simply have to make a change to the boot.ini file and then choose that version when you boot or make it the default from the bios. In PC CS3, the number you see in PS prefs is the max it can see minus anything you have running which is using RAM. So, remove all your software that doesn't absolutely need to be running. In the performance preferences, I believe the fastest cache number is 4 in that same dialog box. There are many other features you can have in PS which are huge memory hogs but also very helpful. I want to use at least 100 history states, but that uses more RAM than the 20 default number. You really don't want to run out of history states and then need to go back. Forget about that old 80GB drive. Although it will help to just put the PS swap file on any additional drive, unless it is a large, fast drive (preferable an SSD or enterprise (10,000 RPM+) drive, you won't see much of a change. Perhaps the best thing to do would be to replace your system drive with a Vertex SSD and use the old system drive as your second drive with the swap file. I have CS4 on a MacBook and it took 25 secs to open CS4 for the first time after reboot. With the OCZ Vertex SSD it now takes only 5 secs which is half the time of my brand new Mac Pro with a 7200 internal system drive. You best bet after the SSD would be to upgrade to a 64 bit OS and have more RAM available!
