hey, ive just bought this card to upgrade my old 8800 GTX. on my old 8800 i used to get around 100 FPS on guildwars, since the upgrade to the GX2, its droped to around 50. im wonder how is this as my brother has the same card and gets 600+ FPS
im wondering if its my PSU as im still running a 650W
also i dont thinks it bottle neck as it would still run at 100 FPS same as the old card thanks
