[Leica] PhotoShop Elements 4.0 on iMac

[bampolsk at mac.com (Brian Ampolsk)]

I'm using PhotoShop Elements 4.0 on my iMac Intel Dual Core running  
at 2.16 GHz.  It has 250 MB storage and 1 GB memory.  I find that  
when I run Elements, it's very slow indeed and also slows down  
everything else on the iMac.  I've always preached that the best bang  
for the buck in computer hardware is memory.  'will it run  
substantially better with 2 Gig memory?  Should I increase to the  
system max of 3  gig?  Has anyone else had experience with a  
similarly configured system?  And, finally, is anyone using Capture  
One LE (that came with the  M8) or Capture One Professional .  If so,  
do either of these products perform better than Elements?  I assume  
that PhotoShop  CS will perform worse, not better.

Thanks in advance for any advice.
