X Star DP2710LED vs ASUS VS24AH-P vs ASUS VG23AH

Hello my budget is $300 and under for a new monitor. I sold my iMac (don't judge) and I am entering the PC world. I do a lot of coding, video editing, multitasking, minecraft server management, SSH etc. I am a full time web host. I prefer 2560X1440p monitors, but lately I've been gaming on my free time and I love 60fps. I heard 1440p and 60fps don't mix well. I'll be playing Minecraft (for fun and to test servers), BF4, COD Ghosts, Skyrim (never finished it), Starcraft etc. I play a little bit of everything. The specs of the parts that I just ordered are as followed:

AMD FX-8350 w/ Thermaltake Frio

GSkill 8GB RAM (will upgrade to 16GB later)

GIGABYTE GA-990FXA-UD3
