1440P 144+FPS GAMING r7 2700 vs i7 8700

[shooter2749]

im doing a sff build and will be using a low profile cpu cooler so nothing more than those 65w processors. I dont care about money so dont suggest i5 or r5 I just want the best performance mainly for gaming. planning on using it for at least 3 years. 

im tempted to buy the 8700 cause its a bit better at gaming but in 1440p the difference is only about 5 fps 

im tempted about the 2700 because if one day I need the extra performance in other thing than gaming its the better option and I guess that with more optimisaiton for ryxzen the 2700 could be equal to the 8700 in gaming

I'm planning to buy a 1440p 144$165hz gsync monitor in the coming year
