Best Z390 Motherboard?
Looking for some advice on picking up a Z390 motherboard. Anything available with the following features?
-Can handle subzero cooling without cold bugging (will be run with a chiller around -30C) and somewhat easy to insulate
-Has the VRM to support a 9900K at 5.5 GHz+
-Can run 2 GPUs at x8/x8 as well as an NVMe SSD. 4 slot GPU spacing would be nice, but can work with 3 slot.
-Can disable specific cores / hyperthreading and can customize voltage/clock speed per core
-Preferably not made by Asus. Nothing against Asus, but have used Asus boards exclusively since 2002, would like to try something different. Maybe Gigabyte, Asrock, or EVGA?
It looks like the EVGA Z390 Dark would work, but at $500 is a lot of money for a "mainstream" board. Any others I should consider?
