Guild Wars 2

Hey all, so I have a problem with FPS when playing in WvW and PvE places where there are more people (i.e Heart of the mists). I know this is expected with most machines but I need to know what people think I should upgrade to resolve this issue.
My spec:
Q6700 core 2 quad @ 2.66Ghz Kentsfield
Hd 7770 1gb
4GB DDR2 RAM
ACER MCP73PV Mainboard
I play at the 1050 resolution, can’t remember the first part.
Lions arch: 15-25FPS
Heart of the mists: 19-28FPS
sPvP: 30-50FPS
PvE zones (questing): 30-50FPS
WvW: About 30FPS when with a small group, but when the zergs come along it dips to 12FPS on High AND low settings?! This is what confuses me!
Hopefully you all will know what the problem is and be able to tell me the best course of action to take to get AT LEAST 25-30+ FPS in wvw.
Thanks all!

Ah thank you for reply, I was expecting just that. Guess this means time to get me a i5 etc.
