I know the CPU, RAM and hard drive are going to make an impact on the RT of any video software. That much is obvious. I am asking what type of gain you get using Premiere Pro 3.0 vs Premiere Pro 1.0 on the same computer. I was under the impression the RT of version 2.0 and 3.0 was better. Is this correct? Has anyone test Premiere 1.0 and compared it to 3.0 for RT? I found out I only have Premiere 1.0. I though it was 1.5. I may upgrade if the RT is better. The Premiere trial demo does not work on my system that is why I am asking if there is any RT enhancement in version 2.0 or 3.0.
