Well Skyscraper, I don't think the Polish site was trying to mislead you. Because in fact, the Videologic Sonic Fury and Turtle Beach Santa Cruz use the same exact sound card design (they even use the same markings and lettering in the back)! 😲
I was puzzled by what you said about the Sonic Fury pic so I went to do a little Google search for it, and found this old review of the card itself:

And this is what took me by surprise completely:
Currently, the Cirrus Logic DSP is used in only two soundcards, the Videologic Sonic Fury and the Turtle Beach Santa Cruz. The soundcard was designed jointly by Cirrus Logic, Turtle Beach and Videologic, and in fact, my Sonic Fury card bears markings of the Santa Cruz!
Right below that sentence you can see a picture of the Sound Fury's back. It's exactly the same as my Santa Cruz! The only reason I never knew about this is that the Sonic Fury was never sold in the US, only in Europe. And since both sound cards look exactly the same, pics of one can be used to represent both. The differences lie with the retail box, drivers, and software bundle. This also means that the Turtle Beach WDM drivers won't work with the Sonic Fury; only the Videologic drivers will work. I'm sorry about the confusion 😢
