RX480, 2500K and a gen2 PCI E x16 slot - bottlenecked?

Hi all

Have been searching the forums and various websites, but wanted to tap into the overclockers brain.

I was looking at getting the latest Doom game, and maybe a couple of other modern PC games but think I need a Graphics upgrade to get the best of them as my machine is a few years old (will be playing at 1080p, maybe 2550 if I get a new monitor next year)

The AMD 480s look interesting and in my price range (circa £250) but before I push the button I wanted to check that the rest of my machine won't bottleneck it. I was going to get the 4GB version as 4K gaming is a long way away for me.

I have an overclocked 2500K which has been sitting at a rock solid 4.5GHz since I bought it years ago (incidentally still the best value for money processor I've ever bought). It's plugged into an MSI P67A GD65 motherboard which has a PCI E x16 Gen2 slot. I'm running 2x AMD 6950 graphics cards in SLI at the moment which are getting a little long in the tooth, as well as SLI not really being supported well enough to make enough of a difference.

If the 480 would be overkill and bottlenecked either by the Gen2 slot in the motherboard or the processor (probably not the processor, given how few games multi-thread past 4 cores), then what other upgrade would get me playing the latest Doom, maybe Battlefield 1 or Total War: Warhammer for a sensible price?

Don't fancy upgrading the rest of the machine just yet, especially given I don't edit video etc so the 4 core 2500K is still more than adequate for my usual workloads.
