Throwing in more memory will not automagically speed up everything.
Better search for the bottleneck.

Is your CPU too busy?
--> watch the ouput of "top" while requesting yout website

Do you have permanent slow queries, which burn your CPU?
--> log slow queries and use EXPLAIN to find out what is going on.

How effective is the query cache?
--> use mysqlreport or SHOW STATUS LIKE '%Qcache%'. The higher the ratio
between Qcache_hits and Qcache_inserts is, the more effective your query
cache works (e.g. 10:1 is good)

...

Which extensions do you use at all?
