Thanks for all the input. I did a good bit of research and after looking at monitors decided to go with a 27" (2k - 2560x1440 - WQHD) Asus PB278Q. I didn't have room for a 32" but this fits perfectly. I used the Win 10 feature to up scale to 125% and everything looks and reads just like my old 23" unit. The increase in size and resolution is a definite upgrade. P3D looks great and my GTX 970 is able to handle the extra pixels with no problem.
4K will probably become rather standard in the future but 2K is a nice managable upgrade for now.
