Personally, when I buy a new computer I try to get the most powerful setup I can afford so that I don't have to buy another system two years later when the current one is unable to handle the programs I run without issues.

A lot of memory, a good grafics card and fast and plenty disk space. And than the fastest processor you can buy.

Your question sounds like what is the best car. There is not one solution. But generally for film "a lot of" and "fastest" is never wrong.
