What a load of nonsense.
When a company does well, this generally gives them room to invest further. This, for example, is why NVIDIA's R&D budget has been able to climb over the last several years while AMD's has shrunken. NVIDIA can simply afford to invest more to realize the products of tomorrow thanks to the financial successes of today.
If you genuinely think that a company like NVIDIA (or any reasonably well run tech company) will say, "oh look, we're profitable, time to hit the brakes" then you really have a poor understanding of business reality. In the fast paced world of semiconductors, you can't afford to rest on your laurels lest some other hungrier/more aggressive company comes in and starts ripping away market share from you.
R&D cycles for these products are on the order of YEARS, so it's very difficult to recover from a screw-up (see: Bulldozer).
Anyway, if you look at the trend in NVIDIA's R&D you can see very clearly that they aren't just kicking their feet up and coasting; they're investing more today because that's what it takes to be successful tomorrow.
We know Nvidia is investing in R&D. The question is why is support for older gen cards so underwhelming. Nvidia's shady tactics are more designed towards accelerating upgrade cycles as they leave the n-1 gen users hung out to dry. This manipulation of user upgrade cycles is what is being argued about which you are trying to evade. Anyway hope you are being compensated for your staunch defense. :thumbsup:
