Gigabyte Z390 AORUS PRO WIFI

The Z370 AORUS PRO WIFI is a close match with the previous one, it has almost all the features the other one has excluding a few, and that’s why we chose to make it the top #2 on the list.

It’s a beautiful board however it does not have the auto overclock tuning that the MSI Z390-A PRO had, and it does not have onboard wifi either. These are the 2 most important features that it’s lacking when compared to the MSI Z390-A PRO, there are a few more differences, but they aren’t as important as these. However, it’s also cheaper.

If you don’t care much about the overclock auto-tuning nor the fact that it comes with no onboard wifi, then this may be the best choice for you.

The Good

  • BIOS looks good.
  • Tons of 16x PCIe Ports
  • Allows Overclocking
  • Decent Price / Cost Ratio if you don’t mind the missing features

Not So Good

  • No auto-tuning when overclocking
  • No Onboard Wifi

However, this one isn’t much different from these 2 it’s quite cheaper than both of them, it has an excellent price/performance ratio, and that’s something we value a lot!

While it doesn’t look as good as the other 2 motherboards it’s still capable of doing its job properly, it even comes with the overclock auto-tuning that the AORUS PRO WIFI didn’t have! There are a few downsides that don’t quite make it as good as the other 2 but other than that, this motherboard is a perfect choice for anyone wanting to save some money while still making sure they’re buying a high-quality motherboard!
