That's a very good question, and one that is going through wild speculation so far. I've seen reports that say it could be 30%, and I've seen reports that say it's not noticeable except in very specific, seldom used edge cases. I expect the truth lies somewhere in the middle - It's not going to be huge, and on the average consumer computer won't be a big deal. But when you look at things like server farms with thousands of machines, even a hit of 1% can be significant. It'll have a bigger affect on widespread Cloud-based applications than anything else.
