I'm kinda stuck in the middle of the two.
I LOVE nicely detailed games and actually DO stop to notice the purty textures. But I also dislike it when my games slow down at all...
Couldn't really lean towards either.
I usually adjust my settings for which game I play (sometimes I don't really care).
But if I'm gonna be in a fast shooter-style game, then I'll turn performance up & detail down. Whereas if I'm playing a strategy game like Age of Mythology, I'll turn UP the detail so it's easier on the eyes.
