Intel CPUs support Pci e 3.0 while AMDs don't? What's the difference in performance if I used a Sapphire R9 290X

First up I'm a complete noob in building PCs. :??: 

So I'm planning on building a PC which should run BF4 and similar games on ultra in a smooth 60fps, or should I say, a Gaming PC. I planned on going with AMD for the processor as it delivers similar performance for a lower price. I AM ON A BUDGET OF AROUND $1200!

The Graphics card I'm going for is the Sapphire Radeon R9 290 Tri-X OC (this thing is a beast for the price they say) and I saw that motherboards that go with AMD's CPUs/APUs do NOT support Pci-e 3.0. The graphics card requirements says it's interface is Pci-e 3.0. However if I buy a motherboard for an AMD processor and use whatever Pci port (the best available) that comes with the motherboard, will I not get the maximum performance out of the graphics card? Or would the graphics card even work with anything else other than the Pci-e 3.0?

It would work on a PCI-E 2.0

I am currently using an HIS R9 270x and it says on their website that it's interface is PCI-E 3.0 but the motherboard I'm using has PCI-E 2.0 so no worries. I also use AMD processor. ^_^

A PCI-e 3.0 card will still work in a PCI-e 2.0 slot even if the CPU doesn't support 3.0. The difference in performance terms between the two standards is minimal.

Wait so do the motherboards for AMD processors lack anything else that'll give bad performance(On a good mobo)?

On a good motherboard then none.

the diffrence between pci-e 2.0 and 3.0 is bandwith, 3.0 8x = 2.0 16x, 3.0 4x = 2.0 8x, but it doenst matter because it takes a dual gpu (+1500) card to hit the limits of a pci-e 2.0 x8 (3.0 x4)connection, so in practicality, there is no detectable diffrence

not yet!! i believe when direct x12 comes out pci 3.0 will be the way to go for sure. just my opinion

for graphics cards it doesn't matter we have jet to fully saturate pcie-2.0 with our current graphics cards, the only thing seeing improvement from pcie-3.0 would be storage devices at this point

PCI-E 2.0 Won't bottleneck a noticeable amount.
