'Seam's like it's down to individual system's as to how P6 perform's? I'd still bet that at the end of the day it will all come down to software conflict's! I have a friend who has an identical PC to mine, exactly the same hardware made by the same person and his P6 run's just fine 'difference is that he has completely different software interests to me and that's what makes me so certain....Yep, all down to what other software resides on the same drive as P6!!!
