> Generally those with the top end CPU have the top end GPU and the top end monitor I sort of doubt this is true, if only for the reason that most people don't buy a new CPU, GPU, and monitor at the same time. monitor and pc are probably going to be on different upgrade cycles, unless the monitor came with the pc (in which case, probably not "top end"). for DIYers, the GPU and CPU+RAM+mobo are likely also on different upgrade cycles. I bought my current 4K monitor about four years ago, but I ran most games at 1080p until I had enough spare cash to buy a 1080 ti. I finally upgraded my CPU, RAM, and motherboard this year, mainly because I was tired of having 8GB of DDR3. in any case, it's usually not a rational use of funds to buy the fastest CPU and GPU for a 4K monitor unless your budget is unlimited. with a constrained budget, it's usually better to drop a tier or two on the CPU if it gets you the next higher tier GPU.
