If you took the x11 or x13 or any other algorithm and compared the hashing power of a cpu vs GPU it wouldn't even be 1%.
I really don't know if this is just to much for you all to understand or if you just like to troll.
Do you really believe in what you are saying? My Phenom X4 CPU was able to mine Darkcoin (X11 if any) at 200-300 KH/s (I don't remember exact numbers), while R9 290 can do it at 8 and higher MH/s. 40 times faster roughly (40 000%). So who can obtain more profit (and who is the throll now)?
