Ghosting is something that cannot be gotten rid of entirely IMO, whether or not it is visible is subjective. Personally I don't see it on my own one unless I look closely at the mouse pointer. It is rated 12ms Black to black
I would ignore gtg and look for reviews or at the least black white black response times.
Also, I am unsure what you mean by videophile, you are using a TN based LCD and those are crap visually.
