Does x8 really bottleneck?

[Macoco]

For work, I have a Hackintosh for final cut pro but I noiced that my processor only has 16 PCI-E lanes and that my GTX 780 is using up all the lanes. If I were to install a 960 evo m.2 drive, would it bottleneck my gpu? The drive uses 4 PCI-E lanes for reference

there are anouther 20(ish) pcie lanes from the chipset for things like the ssd, nics, usb 3 and wifi.

 

8x won't hurt performance

 

We need a stickie for this.

no. Not even 4x does. below that, yes. provided it is pcie 3.0
