Interesting preview, thanks OP! Rep+

1. The GPU sees a nice bump, but just to keep updating the yearly performance, the GT3 for laptops is what should give a considerable bump. Of course, desktop users won't see it, unless we are talking about mini-ITX mobile based systems or iMacs.
2. This is a preview with no discrete cards gaming results, so we'll just have to wait for more previews or the final reviews.
3. What is the overclocking like, and do the CPUs, especially the K versions, use TIM or solder ?
4. What is the power consumption like ?
5. In terms of CPU performance (however results for gamers may change this perception, see nr. 2), this is a step up in almost exactly the same performance difference as going from SB to IB. In fact, apart from Visual Studio which saw a considerable bump , in a way this just goes to prove that Intel has such fantastic engineering resources that they can tune the final performance to this degree at equal clockspeeds. It also means that in terms of CPU performance they are kind of idling, waiting for AMD to catch up. But they are also playing their cards right when it comes to IB-E, which they have to keep a valid consideration for enthusiasts when they release them later this year.
