Actually I just thought about something interesting...
For gaming POV, for those hardcore elitist especially, I realised how much u going to upgrade ur component depend solely on ur display.
In short, u upgrade to saturate ur display, which bring to me to a point that a monitor display might become the most important aspect of gaming rig component.
Ur budget depend on how much u spent on ur screen, and subsequently how powerful you want ur Rig specs to be in order to utilised the display specs.
With 5K/8K coming out and DP1.3 / HDR + OLED + >120Hz, not to mentioned VRR support, it becoming more and more important main specs to determine what component u are going to get to support it.
No more waiting for new CPU or GPU, a true hardcore enthusiast should be waiting for the most high end display, don't u think so?
