Re: Upgrade IMac 333 for OS X
I'd suggest you do the following:
- Install OS X on your machine as it is
- Run it for a few days, doing all the sorts of things you'd usually do with it.
- Take stopwatch-timings of apps starting up and switching and jot them down. Keep the terminal running top open so you can see how much of your RAM and virtual memory is being used.
- Then, from terminal run vmstat (virtual memory statistics) to get an idea on how the system is handling virtual memory.
You'll probably find it is using a lot of RAM and VM, in which case upgrading the RAM will really improve the performance on everything but application start-up. I'd highly recommend upgrading the RAM as the processor has faster access to this.
Don't go overboard, though, as you'll never really squeeze a lot of speed out of the 333 due to a combination of processor and bus speeds. Just get enough RAM to help take the workload off the VM, and don't dig any deeper into your wallet than you need to.
