Matching GPUs and CPUs?

[Riposite]

Is there anyway to know if a GPU bottlenecks the CPU or vice versa without having to test it? Like, can I know if this CPU is a match for this GPU by the GPUs specifications? or, is this GPU a match for this CPU?

I think checking the benckmarks if a better CPU delivers a much higher framerate means the weak CPU is bottlenecking, otherwise : no.

You learn to remember them after a while. 

 

You can always Google though.

heating the system up with a demanding game and looking at the load graphs will tell if your gpu is for example at only 50% while your cpu is breaking a sweat or the other way around - thats one way to find out but its not always that visible.

You can't tell from the specs, you need to see benchmarks. Either way as @PassionFruit pointed out, after a while you just "know". Which cpu and gpu do you want to match exactly?
