I will be playing games like Skyrim, Tera, and Tomb Raider. I don't know if I should keep my motherboard, the Asus P8H77-I Mini ITX LGA1155, or if I should change it to the GIGABYTE GA-H77N-WIFI LGA 1155 Intel H77 HDMI SATA 6Gb/s USB 3.0, located here:
Don't get a PCI-E WIFI module. ITX boards only has 1 PCI-E slot, putting that wifi module in means playing games with IGP only. I prefer the Gigabyte board more due to better board layout ( sata ports placement on P8H77-I is pure crisis ), plus it's cheaper than the P8H77 I at the moment. Those and the integrated wifi module with long antennas make it the clear winner.
