xiphon, not personally, but some programs such as Final Cut Pro, Logic Studio, Photoshop etc. can require significantly more than 4GB of memory if lots of plugins are being used.
You can request for the program to open in 64 bit mode (rather than just 32) whereby it will help itself to as much of your system memory as it pleases, rather than topping out at 3-4GB. I’ve seen instances of 100’s of plugins being used on a system with 16GB of RAM iirc, and it was munching through the lot!
If 64bit offered no advantages ever, we’d never fit more than 4GB of RAM!
But yes, for the average user, 32 bit is still going to be fine for many years to come.
Did you ever get my email about the Hackintosh by the way? I was in dire need of help at one point, seem to have fixed it all now though. FINALLY got my wireless Vs 4GB RAM issue sorted out (wireless wouldn’t work unless I removed 2GB of RAM!)…
