I have spent several days online reading product and customer reviews and brushing up on what's the latest greatest of Motherboards, CPU's, Memory and Graphic Cards. It appears my decision to rebuild CoolerMaster Tower gaming PC is at the crossroads of Technical changes. The newer Processors appear to be heading towards the Intel LGA 2066 sockets, with AMD doing the same.
My old Gaming PC was a total Nvidia Build with Motherboard and SLI Graphic cards with an Intel CPU and high speed RAM. I have a 2014 Asus ROG that's been fantastic, but as anyone knows, 5 years makes even the best of PC a dinosaur.
The consensus I have gotten is that Asus and Gigabyte are like Intel & AMD, all having their Pros & Cons.
It comes down to what you use your PC the most for and to buy or build one within the budget you have as best you can. My own problem is getting through what's available in a Motherboard that can handle the basic Peripherals (CPU, RAM & Graphics card) without losing what the best of each can bring to the combination of them all together. I keep finding which ever I choose, there is a compromised loss to one or more of the others. Still studying and searching for the answer. LGA 1151 (300 Series) or the LGA 2066. The LGA 2066 Motherboards seem to have issue limits with the Intel X Skylake & Coffeelake CPU's, RAM and SLI I'm trying to find a solution to. I agree that so far that Asus or Gigabyte are both a good choice for reliability and support..
