Switch from Mac Pro to MacBook Pro + Monitor

[R.Youden]

I am currently in the market for a new laptop. I have seriously been looking at the new MacBook to go alongside my MacPro. However I was thinking earlier that I no longer really push the MacPro to its limits (I have finished the work I was on when I got the machine) so maybe I could ditch the MacPro and it's Dell 20" monitor and go for the 2.8GHz MBP + 24" monitor.

How much of a performance loss would I see? 10%, 25%, 50%?

I know that is a difficult question but any ideas?

Thanks.

It depends on the programs. If you're using a very CPU intensive application that uses the quad cores of your MacPro, you're talking orders of magnitude faster than a MBP. I don't think you would notice the difference running web browsers or wordprocessors etc. If you're doing video editing or things like that it'll be a definite slow down for you. With video editing a rough estimate would be like 20-40% slower with a mbp
