Here it shows on my PC. fresh install of Windows 10. This MB is low cost, yet feature filled, especially for an AM3+ one.

This was installed on a custom build that was given to me, the prior MB was a Gigabyte that didn't have AHCI for my SSD's, nor UEFI firmware, the latter of which I wasn't looking for, yet a bonus to have. I've ran this PC with this MB for hours on end with Windows 7 Pro before the upgrade, and finally set all UEFI defaults (except Secure Boot) and Windows 10 Pro Rocks on it.
If this were an Intel 1150 Z97 MB with this many features, would had cost upwards of $90. The dual width GPU doesn't block the x1 slot as many does, and if desired, one can run two GPU's.
Like I stated, and I looked for 4-5 days before pulling the trigger, this MB for the mATX is unbeatable. Even if the price was higher. Though I didn't know when ordering, the case could had held a full sized ATX MB, but would had been a very tight fit, as it was tricky to get the mATX MB in there with the PSU & drives in the case. The drives & bay would had to have been removed for the ATX MB, where there may be more options.
My next upgrade will be the FX-6300!
