Guild Wars 2

My specs:

Gigabyte GA-P55-USB3
Core i7 870 @ 4Ghz (results at stock speed are worse)
2x MSI Cyclone HD6850 OC edition CCC 12.8, profiles 12.8 CAP2 (using crossfire hurts framerate by 30%-40%, so I’m running the game on one card)
8GB DDR3 Kingston Value Ram 1333mhz (9 9 9 24)
2xOCZ Agility 3 in Raid0 (the game is installed on the SSD)
850w Corsair Power Supply
Windows 7 SP1 x64

Playing the game at medium/high settings
Everything on high except shadows, reflections, LOD, shaders and post-processsing.

PvE: In nearly all zones solid 60fps (heavely populated zones 50-60fps)
Structured PVP: Solid 60fps
WvW: Every battle that consists out of more than 6 people makes my framerate drop to 30fps (CPU usage @ 50%) it rarely dips below 30fps (even in big fights), changing settings does not yield increased framerate. I suspect it’s not GPU/CPU related (both are not at maximum capacity), panning the camera to the ground/zooming in does not increase framerate (one should suspect it to if it was GPU related).
