I think there are basically TWO answers to your question.
The 290 HP (or a little more with some basic mods) is more 90% of your driving more than enough.
The NSX is a relatively light car, especially compared with the current crop of heavy sedans that all seem to weigh well over 4000 lbs with a full tank easily.
So, in essence, with around 300 HP, the NSX is quite capable of hanging with 350-400 HP cars that are a lot heavier. I've never had much problem with keeping up with the 325 HP Porsches, the 340 HP E46 M3's or the 420 HP RS4's. And I never had any trouble with cars like the Golf-R or Audi RS3 or all the various GTI-models.
BUT, in order to do so, you DO need to work your car and make maximum usage of that high RPM-limit and all your available gears.
At the same time however, the NSX is ment to be a SPORTScar, which usually stands for high performance. So, in todays car-market, the standard NSX IS getting cornering by the current crop of fast hatchbacks.You might be able to keep up with the new 300 HP hot hatches, but it is getting increasingly more difficult as time and developments move on
Even the new Civic Type-R wil have around 300 HP according to Honda.
So, a little more power comes in handy to make sure the NSX isn't becoming a sheep in wolves' clothes. I've been driving a NA-NSX for years and had lots of fun with it, but ever since I have the Comptech SC, that fun has simply increased
With the CTSC I have found that I can quite easily keep up with the M5's, C63 AMG and the latest Porsches (Turbo and GT3 excluded). And THAT is even more fun because their drivers simply don't expect that. And this of course in a straight line, I am not even talking about cornering yet
