I am currently torn between the LG 34UM68-P and the LG 34UC79G-B. The 34UM68-P is more accurate in color (sRGB over 99%) but restricted to a 75hz refresh rate. However, the 34UC79G-B sports a 144hz refresh rate but is less accurate in color (NTSC 72%). Which should I buy? I will be mostly gaming...
