which amd cpu can handle the most graphics processor power

[Super_]

and what is the highest gpu that the best amd gpu wont bottleneck so much.

I would recommend an OCed 8320, that should be able to support a 980(Ti) without bottleneck. The 6300 can do up to a 970.
Overall, you will get better performance on the intel side. Not just higher peak FPS, but higher minimum FPS as well.

would an 8350 do better? and the amd 9000 series arent worth it because theyre just overclocked cpus from the 8000 cpus right?

The 8350 is just an OCed 8320, so if you OC yourself they will perform identically.
The 9590 and such are simply binned 8320s that are factory OCed.

ok a couple more questions. if i get a cpu in the 9000 range, will it handle more graphics power, and does pcie 2.0 support crossfire or sli?

They are not worthwhile processors, as an OCed 8320 will perform nearly identical, and support the same GPUs.
PCIe 2.0 does, so long as they are running at x8 mode or higher.
