I just upgraded from a

2xIntel Xeon-Harpertown 5450-Quadcore,16 GB,Redhat EL 5.1-64
To
2xIntel Xeon-Nehalem 5570-Quadcore,36GB,Redhat EL 5.3-64
 
Any advice on how I'll get the best of this server?

This is what I currently have:
max_connections = 100
shared_buffers = 2048MB
maintenance_work_mem = 128MB
max_fsm_pages = 1000000
bgwriter_delay = 10ms
bgwriter_lru_maxpages = 0
wal_sync_method = open_sync
wal_buffers = 2MB
checkpoint_segments = 64
checkpoint_warning = 270s
archive_mode = on
effective_cache_size = 5400MB
default_statistics_target = 500
logging_collector = on
log_rotation_size = 100MB
log_min_duration_statement = 1000
log_connections = off
log_disconnections = off
log_duration = off
log_line_prefix = '%t'
track_counts = on
autovacuum = on
statement_timeout = 5min
