A couple generation of X11 ASICs are out for a while so GPU mining X11 is long pointless but now not just earlier generation ASICs got downgraded into doorstoppers but even the newest, current generation ASICs might not make their investments back considering some people still haven't gotten theirs and how flooded the market is.

We have Bitmain D3 (15Gh/s), PinIdea (17Gh/s), iBelink (10.8Gh/s), Baikal (0.6Gh/s), Innosilicon (30.2Gh/s) that I know of.
