I would agree that RAM might be more important. I have an Intel Celeron (not sure about the speed) with 256K RAM. P5's a little pokey, but OK if dealt with patiently. I had a couple of messages about Virtual Memory running low, so that's why I recommend RAM. (BTW, I'm an old-timer when it comes to 3D packages. Just think of those slow times as times you can reacquaint yourself with your cat...)
