Yes anything X Performance will work with the X. Everything I've ordered actually has been for the Performance. I just received a new case for mine this morning. It's so slim and low profile that you can't tell it's on there. I have a frosted white and frosted grey of the same case which also provides full coverage. I also just put a full body skinomi coverage on it with the back piece being a silver carbon fiber. Pretty cool looking.Will accessories for the performance fit the x
