Help Please

You would get like a 30% boost id say no not worth it, just overclock the560, unless you went for something in 7900 series

Yes it will bottleneck but not much like somewhere in th low 5% same as your 560 is bottlenecked

Is Bottleneck ok? Or how do i fix iT?

You can get this

No bottleneck. But if there is, it can be dodged by overclocking your CPU.

its onlly 5% id recommend just leave it as is

So i can get a 7870 and it will work fine with my CPU?
