I need to get a couple of new 32GB cards and previously I've always gone for the Extreme Plus (80MB/s) cards but wondered if there's any benefit from the Plus version?
I was just about to post exactly this! I used this website to work out how best to match SD and CF cards on a d800. It definitely helped me not spend too much on the top of the range cards.As noted above, the end result depends on both the card and the body. In the 70D's case, you apparently run into a ceiling at about 36MB/s, with the Extreme Plus and Extreme cards faring virtually identically.

But I go for faster cards so can upload to computer more quickly too.

At the risk of hijacking the thread (eep!) - do you know if the D800 writes to both cards literally simultaneously, when configured for "send everything to both cards", or is it like the D7x00, where it will write to one card, then the other, thereby taking twice as long? (Of course, the time I experimented with that configuration was the day when the local rabbits were in feisty form, so I was running repeatedly into the D7100's *ahem* bijou buffer. Thankfully, rarely an issue. Still, knowing the cards are capable of around 3fps and hearing the shutter release much less frequently when there's a frenetic chase going on.. live and learn)
Writing to camera will be limited by how fast camera can write. But I go for faster cards so can upload to computer more quickly too.
