Noticeable performance drop on all my systems, i have done fresh installs on 2 systems of win 7, 8.1 and 10 to compare , windows 8.1 is way faster on both systems whilst on windows 7 is faster than 10 on one of them, so performance wise Windows 10 is a bit of a miss on current builds.
Currently the wife's laptop and the Lenovo Yoga are running 10, had to fix a few issues with 10 on her laptop, rarely use the Lenovo.
Win10 runs the same as Win7 did for me performance-wise, only heck of a lot buggier and the 'Store' broke early on, few months ago, as well as the apps. that rely on it . . . don't really miss that bloatware though. No update ever fixes it, so letting that go.
Never had any problems with Win7. Lots of start-up config. problems with Win10, that only the Macrium Reflect Rescue Media disk can cure. Win10 Repair Disk does nothing to fix start-up problems.
-this is a sample of my Windows 10 reliability:

I run some benchmarks on same system in dual boot with W7 Sp1 and same drivers. Had 1 - 10% better marks in W10. Graphics well within 1 - 2% but that's pending Dx12 titles which should give it a good boost.
Best fared memory with up to 10% boost and that was before memory handling changes. Since than I changed to 1866MHz so now I can't compare with old results in W7.
SSD is now running better but I attribute that to better AHCI drivers for my MB.
As far as processor is concerned, it seems that load per core is reduced in W10, load is spread over multiple cores better although benchmark score stayed same. In heavy multitasking there's no more of some cores hitting 100% while other sit idle, not even with single threaded applications.
