Remember, hand-me-downs help build character and character is good. :D One last thing that I'll suggest checking is your texture spooling settings. (File => Preferences => Imaging/Scratch disk) If your scene is texture map rich, you might want to set the memory reserve to 800M or so (based on 2G of RAM). If the textures aren't super high resolution, you can dial it down to about 100M per Gig of RAM. I routinely keep mine at a little over 500M. Depending on what's going on on your system, this may or may not do squat. But it's worth a try. And, addiction is a good thing when it's Carrara. ;)
