im looking at getting this display for gaming.currently im rocking a sapphire 7970 vapor x 3gb but will be getting a 980ti. from what i can find online it dose have 4:4:4 crome and can only be run at 4k@60hz if connected to an hdmi 2.0 graphics card. can anyone that owns this tv tell me how well it runs and if it will run at 60hz at a lower resolution or would I be stuck with 30hz untill i get the 980ti? im ready to buy this. just need to no these things before i go ahead.thanks
