basically a good processor is nothing without cache and lots of ram. Most people think the if they get a fast processo, then the computer will be fast. But its not true, what you really need is a good processor (not something fast as hell) and a good amount of ram. That way your computer will have more pages and frames in the memory so that when the processor calls for the pages then it will all be loaded in the memory and not on the harddrive (virtual memory). Virtual memory is good but u dont want to rely on it. What you want is lots of memory. Something like ddr 2700 or if you can get a laptop with a centrino processor and lots of ram. The processor speed shoulnt be your choice maker. By the way, have you looked at toshiba yet?
