Will a r9 nano bottleneck a amd a8 7600 apu?

Solution
1st, GPU don't bottleneck CPUs, CPUs bottleneck GPUs. And yes, with that combination the Nano will be bottlenecked like crazy. The A8-7600 is not fast enough to keep the nano fed.

2nd, you can't enable dual graphics with the A8 and the Nano. Dual graphics on the A8 only works with the R7 240 or R7 250. Just the nano will be faster than any combination of dual graphics.

You can buy it and use it without issues, just don't expect it to perform extraordinary. Maybe you'll get 1080p mid-high.
