Pluspunten
There are tons of extremely intelligent people to work with; NVIDIA offers decent compensation (not quite as glamorous as Google, but pretty standard offerings including full health benefits and decent stock option benefits with a faster vesting schedule than other companies I've worked for). Also, NVIDIA provides employees with all the latest cool computer toys you could possibly imagine - obviously, high-end video cards, but also gorgeous monitors.
Minpunten
There are a lot of people here who work very long hours, and if you aren't careful you can easily end up burning out. The company doesn't do 401k contribution matching, which I was surprised to find out. Parking is kind of difficult sometimes at the Santa Clara office because of how many people we have in our offices.
