DXO and road bikes

Why road bikes

We could talk high end stereos, cars, etc. etc.

The bottom line for people who upgrade or want the best is what is "best"

There is another crowed that actually use the equipment and for them sometimes that little incremental bit is a competitive advantage either physcological or real for the creator or the buyer.

I'm on the fence for the D3s --> D4. If I just peep or go by DXO there is no reason to upgade, but just the FPS might be enough for me. Shoot 3-5K shots a day 3-5 more stunning keepers, that is enough for me!
