OK, we're talking about two different things.
Translating that into "modern times", a Linux box *should* be able 
to competently run MySQL and Apache at the same time.
And it can.  If it couldn't, Plesk would not be selling.  In my job I 
admin servers that do web, mail, and db for anything from a handful 
to 1200+ domains on a single box.  No problem there (mostly).  But 
the load on the server's resources are, in the end, down to to what 
your application does.
There are several good reasons why you might want to put your DB on a 
separate server.
The grumpy geezer in me says you make a dedicated DB server only if 
your hardware and/or OS isn't up to snuff, or your RDBMS is a horrible 
pig, and that any modern desktop PC should have enough juice to 
support an RDBMS, dozens applications and 10,000 OLTP users.
It depends on many things. I have a intensive applications and I need a 
server with separate RDBMS. I have a +200GB database size and need to 
increase to a minimum of 1000GB (to save more old data to report purposes).
You need to think on many different architechtures and needs because for 
many web sites you don't need a big machine, with a PC you should run 
web server + rdbms without problems (even to many domains on this single 
machine...) but there are many companies that can't run web server and 
rdbms on same machine, even have many RDBMS servers and a lot of web 
servers, to achieve a good performance and high availability.
Bah humbug.
We supported 70 on-line users *plus* ran batch jobs on a
pathetically slow 1980-vintage 1.6 MIPS machine with only 6MB RAM.
MySQL runs on commodity hardware but if you are doing 1000 statements 
executions per second, you need to think on a good hardware if you want 
a reasonable performance.
You young whippersnappers in your fancy cars!  In my day, sonny, we 
walked uphill to school both ways, AND LIKED IT!
