Q: Will this be a good upgrade from the Gigabyte GA-78LMT-USB3? Also, will this support a MSI NVIDIA GeForce GTX 1060? I'm looking to upgrade my system to run my games smoother but i don't really know where to start..
Answer by Website User on 22nd August 2016
A GTX 1060 will work fine on this motherboard. Upgrading the motherboard by itself wouldn't have any significant effect on performance, unless you're also planning on replacing the processor and potentially memory as well if your current memory is a lower speed. -Danlevan
