Low frame rate, need suggestion

Hi, I got evaluated "Very High" score when run benchmark at maximum resolution.
Log is here,

FINAL FANTASY XIV: A Realm Reborn Official Benchmark (Character Creation)
Tested on:20/12/2013 19:17:36
Score:6980
Average Framerate:59.017
Performance:Very High
-Easily capable of running the game. Should perform exceptionally well, even at higher resolutions.

Screen Size: 1920x1200
Screen Mode: Windowed
Graphics Presets: Maximum

But on actual game, in uncrowd area, frame rate can barely touch 40 fps on Standard (Laptop) setup and 10-20 on Maximum

My PC spec as following
CPU : FX4100
Graphic : Redeon HD 7870
Ram : 8 GB DDR3
HDD : WD Blue (or Green) 5600 rpm (or 7200 rpm)

Looking to upgrade in this new year but I am not sure if problem is at CPU or HDD or somewhere else.

Editted : But I can run on maximum set up really fine in dungeon with 60 fps

Please give me suggestion.
Thanks. ;)
