Aye, i know i'll be taking a big loss on the sale price but i knew this when i bought it back in June.
As the owner of a 3900XT that's actually worse than an average 3900X (lesson learned with refreshes) I feel your pain. I bought this chip on XT release day for £520 and I'll be lucky to get £300. I'll probably end up keeping it and shipping out the 3600x instead to take less of a loss.
