For example, so that the server is purely for the database.

Answer 1

application servers and background tasks (unicorn/php-fcgi/apache-workers/resque/etc) -
cache server processors and cores/search (memcache/redis/sphinx) - database memory
(postgresql/mysql) - memory comes first, on the second disks,
balancers (nginx) - processors and cores
distribution of content / static - disks
something like this, but this is all too simplified, you need to start from tasks and architecture.

Answer 2

>> What is more important to him? Number of RAM or number of cores?
What will the DB do? Structure, etc., everything depends on the task.
>> For a server that gives statistics, what is more important to him?
What statistics, volumes, how is it collected?
>> And the server that handles the requests?
What requests, quantity, data types, etc.
In general, you need to dig in the direction of system architecture, start designing a service, it will be clearer there. And no one can answer these questions for you. There are too many uncertainties.

Answer 3

If you still don't know what resources your applications will need, take a cheap server with a couple of sockets for a CPU, a couple of regular raid hdds and 16GB of memory. Why throw money where it is not yet known? If so, then add if needed.
