"An intel i5 is 50 % better than the processors the consoles are using" according to a test conducted by Rock Paper Shotgun.
It's not just the amount of processing cores but the architecture of the CPU itself. That's also why an Intel i5 (4 cores) is easily compared with an AMD FX 8xxx processor (8 cores). The "power" of a CPU is a relative term since it depends on Cache (L2 - L3), bus, memory controller, instruction set etc. .
Anyway, what I can say about your question is this: Yes your pc is "future-proof" since both your CPU and GPU are considerably "powerful" as well as the amount of your RAM (I'm talking about 1080p gaming. 4-K gaming is another topic since it is really demanding. I can only guestimate since the gaming industry is a vast-growing one and visualization technology is expanding fast and that's why I've not included 4-K in the conversation.).
