You need to understand where the bottlenecks are in your system as you currently use it, before trying to throw random solutions at it.
Look at Activity monitor during your typical usage when it seems slow. If there's no Disk I/O going on, then throwing money at drives might not make sense. If the CPUs aren't being fully utilized, then faster/more CPUs might not help. If there is a lot of free RAM and little paging, then more RAM might not help.
One of the first steps in solving a problem is understanding the problem.
