No, it does not make a significant difference.  Based on measured data on 
real test PCBs.  Spend you time on bigger issues.

Subject: [SI-LIST] PCIe Gen2 coupling caps

Is it necessary or desirable to cutout the reference plane under the
coupling caps for PCIe Gen2?
If I want to include a model for the capacitor with or without the cutouts
in a Hspice simulation what would be the best way to do this? I likely will
be using 0201 size caps.
Thanks
