Hi Wilkes and all,
No, there's no 'rule' per se, and it's probably no secret that prices will vary from dealer to dealer, or even from salespersons within the same retailer.
It's just more fun to put it in the form of a riddle
Actually, price discussions about the 5080 are really theoretical at this point, since there's no product to be had yet. I nearly bit on a XV-88 the other day (great price, with the SRX cards also in stock), but decided I really would be better off waiting for the 5080.
In other words, all of you thinking of buying an XV-88 or 3080 should be posting here.
Regards,
Chris
