The E5 2687W Engineering Sample I'm getting for $510 (QAMT). The version that supports dual sockets is about $540 (QA92). I've looked into reselling them a bit but I don't think I would make too much off them. Other CPU models vary on price.
First, sure retail goes for $1800 but this is not that, it's an ES which is not officially supported by manufactures and slightly different then retail.
Second, it mainly aimed at servers. It's not aimed at the more general enthusiast market, this makes my target customers smaller.
And third, profit. I'm gonna make stuff up here since I don't know:
Bulk prices: QAMT $450 ea, QA92 470 ea.
eBay going rates: QAMT $580, QA92 $660. How much will evil eBay/PayPal charge me if I sell them at those rates? (Hint: A lot ~$55) Using eBay/PP Calc:
Net profits: QAMT ~$75, QA92 ~$125
The main issues is that it's risky to invest ~$4700 on such a product even with the ~$1250 profit since the demand for this product is not that know and I have no real idea if I could sell them off in a reasonable time.
tl;dr: Profit at ~$100 per chip, but demand is questionable.
Also, that thing you're selling is not a laptop, it's a portable PC. You could bludgeon someone to death with it in one blow.
