No way... I have been working with Lightwave doing 3D animations for at least 2 years. I have been attached to my Quad G5 for 4 years not almost. But today I installed Lightwave in my !&" mab book pro, is not the latest but the previous revision. The renders takes literally half the time, the G5 has 4GB of ram while the 17" has 2GB. Is amazing, I was waiting for January to get the new Mac Pros but now is obligatory. What a difference.
