I would think any gpu would fit just fine with either type of clip even with a backplate.
You may run into issues if you were trying to use something like the EK Vector FE water block with the active backplate.
It's certainly a tight fit.
Once you get it past the clips and fully seated, does it fit better with little to no pressure on the ram clips? It looks like it should unless it's already fully seated.
If you're uncomfortable with any pressure on the ram clips, you could trim them off straight with a dremel tool.
