I use HP Pavilion dv7 computer
Procesor Intel Core 2 duo cpu T6400 2.00GHz
NVIDIA GeForce 9600M GT
and I think that it's enough for premiere cs4 to work properly, but the video screen lags so hard, it's like 1 frame per 10 seconds, I don't use any other softwares at the same time.
It's almost ok, when I try to edit videos made with my photo camera, but I usually film with my pocket cam (kodak zi6, 30fps ) and I can't even edit my footage://
