No ghosting or trailing at all in games, which is what matters. Unless I'm just not very sensitive to it, I don't know, but I've read a lot of user reports on the U2311H and I don't think I've seen a single person to say they have seen any ghosting. That's one thing to bear in mind, pretty much all the people who have bought one of the BenQ VA monitors have said they've seen ghosting on them, however most say it's not that noticeable, especially if you don't deliberately go looking for it. I've also seen a few people buy a EW2420 as well as a U2311H and say they can clearly see there's noticeable less ghosting (i.e. none) on the Dell.
It is, but you can't really compare it directly to a TN panel, people have said it's probably closer to 5ms (or even 2ms) if you do a direct comparison.
Yeah, I've just bought a GTX 460 1GB as my old card died and now the Dell monitor, I'm pretty strapped for cash now
