No, your assuming that the graphics card market would play out the same as intel's market position in HEDT or server. Tell me, how does one apply apply to oranges?
TBH, I can't really be bothered going over something that has been extensively covered by standard business models, and even if the monopoly situation that still requires a continuing product cycle didn't apply*, your basic premise makes no sense at all
If it wasn't for AMD, they'd charge you 2 grand for entry level graphics cards.
Who in their right mind would pay $2000 for a GT 705 when any Intel IGP from the last two generations outperforms it? The same can be said for the GT 605, 510, 430, 310, and 205 before it with either CPU or board based IGP. In fact if you'd care to check, even Intel's lowly Q45/Q43 shades Nvidia's lowest discrete card of the same era (the 8300 GS).
* You'd still need to supply a reason why Nvidia owned upwards of 95% of the professional graphics markets yet still priced some Quadro cards at lower cost than their GeForce line - and still does to this day even with a ~80% market share.
Anyhow, you're welcome to your point of view, but if historical precedent and virtually every tech monopoly market since IBM isn't a big enough indicator then I doubt we are going anywhere with this. Rather than derail the thread any further I'll leave you to it.
