I'm just too happy of Sp3. After I fixed some windows 8.1 buy with some process like SYSTEM, system interrupts, etc etc after to have SOLD the docking station that as to all of us don't work properly with its displayport like the mdp on the device, I started to use 100% of my sp3 for work and since 3/4 days I have many hours of job when the cpu is below 10/12% of usage with the fan practically silent! It's something I never experienced even with the lowest and silent fan laptop I had. With i5 can go even better, with lower temperature of 3/4 degrees in average and so even less need to fan usage to cool the cpu. It's really something magic, the future is arrived!!! too happy!!! Of course it's the beginning of something, we can't pretend to have the best and powerfull machine to make rendering or use with high CPU usage tasks, but just to make an example I use it in finance with stocks and some software even in java taking a lot of resources, and I'm able to manage this, I have usually Skype open, one drive, 3 softwares (with charts), thunderbird reduced to incon, 2 mini software for poker statistics, and pokerstars open, I'm able to be constantly below 10% of cpu. I was waiting this moment since 5/6 years at least, and I was not able to believe anymore to have something like this and with zero decibel fan rumor like I'm having write now while I write you... I just feel the rumor of my finger typing right now! bye!
