Milyen vasat ajánlotok egy webáruház alá?

Hali,

A véleményetekre vagyok kiváncsi, hogy milyen hardvert ajánlotok a következő paraméterekkel rendelkező webáruház alá?
Jelenleg is működik, de kicsit köhög és szerintem a vas nem bírja, az hogy mi van most alatta azt nem árulták el nekem. LOLA következő infóm van róla:

Az hogy majd frissíteni kell a rendszert, most nem ide tartozik.

Nincs sehol too many connection, nincsenek hibák, csak néha baromi lassú. MySQL-ben kb. 3000 tábla van, külön fájlokban, a legnagyobb 30GB, kb. 10 tábla 1-10GB közötti, a többi 1GB alatti, összesen 130GB.
Néha a query/sec:30 ezer is lehet, de átlagban 12 ezer közül van.

Néhány MySQl adat, igaz csak 2 órás üzemidő.

Created tmp disk tables: 28.3 k
The number of temporary tables on disk created automatically by the server while executing statements. If Created_tmp_disk_tables is big, you may want to increase the tmp_table_size value to cause temporary tables to be memory-based instead of disk-based.

Handler read rnd: 36.2 M
The number of requests to read a row based on a fixed position. This is high if you are doing a lot of queries that require sorting of the result. You probably have a lot of queries that require MySQL to scan whole tables or you have joins that don't use keys properly.

Handler read rnd next: 531 M
The number of requests to read the next row in the data file. This is high if you are doing a lot of table scans. Generally this suggests that your tables are not properly indexed or that your queries are not written to take advantage of the indexes you have.

Select full join:109
The number of joins that do not use indexes. If this value is not 0, you should carefully check the indexes of your tables.

Slow queries:295
The number of queries that have taken more than long_query_time seconds.Documentation

Sort merge passes:253
The number of merge passes the sort algorithm has had to do. If this value is large, you should consider increasing the value of the sort_buffer_size system variable

Table locks waited:105.8 k
The number of times that a table lock could not be acquired immediately and a wait was needed. If this is high, and you have performance problems, you should first optimize your queries, and then either split your table or tables or use replication.

Amit én ezekből leszűrök, hogy az adatbázis a szűk keresztmetszet, és eléggé meg van hajtva, azt mondják, hogy a top process a mysqld és kb. 60% CPU-t folyamatosan eszik.
Ezek alapján én valamilyen Xeon E5-ös 8 magos 3GHz szervert, leglalább 64GB RAM-al, SAS 15k-s diszkekkel pakolnék alá.
