Currently I've gone by some great support with building my Gaming PC and have brought it to a good price of $1230.32 (Not including Motherboard). But I have yet to get a motherboard. 2 reasons:
1. When I get one, and look through the specification, for e.g http://www.asus.co.nz/Motherboards/Intel_Socket_1155/P8H77M_LE/ ASUS P8H77-M LE Motherboard, it says it has a resolution of 1920 x 1020. Not 1920 x 1080. Now that confuses me for many reason, too many to list, but can someone tell me why it says that, and if this will effect my 1080p gaming experience I hope for.
2. Which is better, using the on-board Wi-Fi Motherboard addapter vs a external/PCI port Wi-Fi Adapter. And if its better use a External one, would it mess the motherboard up if it already got one?

Specs Below if it Helps!
