I was not expecting it to run as slowly at times as it does. Surprisingly, Secret World runs better, at least for me.
GW2 is absolutely beautiful at times, stunning landscapes with very long draw distances. I know a game is gorgeous when I find myself just walking around and sight-seeing. I've found that many people aren't impressed initially with the graphics but come around after spending time with it. I'm convinced that's because the game is bright and very colorful. Your first impression is that it's just like Warcraft in a cartoonish way, but it really isn't.
MMO's are more demanding now than ever. They stress every aspect of your computer and any weak links will quickly reveal themselves with issues like slow frame rates, staggering, lag and slow load times.
Does it really warrant such a high level of needed hardware to enjoy everything maxxed out at higher resolutions? Yes, because it looks great and it's a complicated game. Most importantly is that it scales very well so if you don't have the hardware for ultra settings it's OK because you can just dial stuff down. I get a rock solid 35FPS at 720P on my T9600/9800M GTS (Both overclocked.) laptop which I won't PVP on but I'll do anything else in the game with and it still looks pretty good. It does pump out the heat while I'm playing though.
To me a sign of a well made game is one that can tax the latest hardware but also scale down to allow slower systems to enjoy it as well. This game does do that.
