Will a r9 280 crossfire bottleneck a fx 6300?

[LUNDY-53]

I currently have a fx 6300 and an r9 280 and was thinking of getting another 280. Would this bottleneck the 6300 if so what cpu should i get?.

yes

nothing amd has running at stock speeds can properly feed 280 CF

though I imagine a 4.5ghz+ 8350 can come close, except in cpu bound situations
