So your issues here are:
1) Newegg seems to be removing bad reviews to hide the coil whine defect
04G-2972-KR
04G-2974-KR
04G-2978-KR
I seem to be able to find plenty of bad reviews complaining about coil whine.
2) Newegg is price gouging because they're selling the card above the MSRP as listed in EVGA's web site.
While I'll assume you grasp the concept of supply and demand, you don't seem to understand *WHY* there are limited quantities of these higher end cards. Low supply + High Demand = Higher cost, and yes... sometimes above the MSRP. It's not like NVidia goes out and states, "OK. We'll make 1/2 million GTX980s, 1/2 million GTX970s, and 1 million of each other card in the 9xx series of cards". What happens is NVidia determines how long of a chip manufacturing run they will have (based on time and resources, primarily).
Now as I understand it, graphic card chips are cast from silicon wafers. Normally, 50-60% of the chips cast from each wafer are non-functional. I'm guessing at the rest of these numbers, but I'd say around 25-35% are functional as low end chips (GT610, GT720, etc..). We'll say about 20-25% of the chips cast from each wafer perform well enough to become your mid-range cards (GTX660, GTX770, etc...). Only about 5-10% of the chips cast from each wafer is pure enough to function as a high-end card (GTX980, GTX970).
Now, certainly, NVidia has a good idea of what their output will be like, but their numbers are never certain. They may aim for 100,000 GTX980s, but they may only actually produce 50,000 before the end of the run (again, just guessing at numbers).
Hope this helps you understand a bit more.
