This is false that it's sovled. For some it may have been some kind of PCI-E card slot issue but in general many of us are still having massive performance issues with the CPU being all over the place.
i7 7700k @ 4.8
1080 ti GTX
3200mhz ram
win 10
All my slots are 3.0. Still bad performance. Stutters, wave looking heat like on hands, skips. 7700k 1080 ti , my performance is still really awful and a huge downgrade.
