ISP vs TN Panel monitor for gaming?!?

[Voprix]

So I am having trouble deciding and a monitor because one is a ISP monitor and the other TN. Now I do not really know all the differences between the two, the only thing I do know is ISP is better looking as far as colors and bringing them out, and TN is better for I think refresh rate. Now the monitors I am looking at does support G-sync and I do have a 970 and going to be SLI 970's pretty soon. Anyway i was just wandering if Getting a ISP monitor will hinder my gaming experience at all. Now i do play games and own almost all of the new ones that have been released.

My preference is definitely for IPS for gaming, but I'm personally more of an RPG player and appreciate the color and contrast of good visuals much more than super fast refresh times. I really don't care about twitch reflexes. If you do competitive FPS's you might prefer the TN screen.
