This may be somewhat irrelivant, as I don't run P6 yet, but I have had memory issues in the past. There is a little program I use called 'mem turbo' that give the user the ability to recover hogged up ram and to defrag the ram and return the unused portions back to the free pool for program use. I have found that it has saved my bacon on many occasions when two or more programs are competing for resourses. I have successfully run both photoshop cs and poser 5 together with only 316 megs of ram using this. (Just don't try to recover ram when rendering lol. Poser get a little grumpy) Anyway, just a thought.
