I wouldn't worry too much, he's talking a ton of rubbish as you rightly noted.
I've actually not long come back from a corporate seminar on Ivy bridge (less fun then you'd imagine!) and in the interim nVidia was a heavy discussion draw point. Topic mainly being quad sli compatibility or rather nvidia being slower than its rivals in support/inclusion.
That being said, most of us agreed that considering its fringe tech at best, we wont hold it against nVidia for being slow/relunctant to heavily invest (or in fact reveal too much too soon) on such a niche consumer market area. nVidia commented themselves that aside from that and some minor issues involving clock errors that things were fine overall.
nVidia have just cemented a key deal with microsoft, involving various OS protocols. The 590gtx was benchmarked and noted as the worlds most powerful and adaptive GPU (over the broadest category range that is) if anything things are looking up in the nVidia camp for a change. 'The distance between us and rival firms is comfortable again' to quote the speaker, which he said jokingly - I read that as 'we are relaxed...for now'
You have nothing to worry about nVidia are good, stable and increasingly investable at the right tiers. Don't listen to junk. They aren't flawless but they are a good product. Make no mistake.
edit: before people start looking at the latest MSI offering - note I said 'broadest range' - Radeon has its strengths. Most of us know the difference
