For those that like to stay up to date with drivers, seems like not so long ago for Nvidea's last driver, they still don't do monthly drivers like ATI do ... but for all flight sims I own I do prefer Nvidea
Back when I used to follow hardware more closely this was sometimes a sign the next gen card might be close, in this case the Kepler named GTX 6xx series ... I'm a hardware enthusiast so would like a GTX 680, depends on the price and performance over what I have already though.

I'll try the new driver later tonight.
