False trade description?
Well, if thats the case go ahead and sue Intel then.
Bro Ongbs took the description from the official Intel website.

TS, why not you just take the processor, and sell it back off on LYN Garage Sales.
No point making a fuss over this anymore.
The seller is not to be blamed as he had never stated it's a S478 and he did post a picture of the pin orientations.
If you had 15 years of experience, you would have recognised at first sight that it's a S479 and not an S478.

I'm supporting the stand that no refund should be made as the mistake is more on buyer's negligence.
