Been using this exact build ==> http://www.youtube.com/watch?v=O6olutcuXHc&list=SPADA5B91FFC11D251&index=7 with the recommended wireless adapter and Windows 8.

And while this PC doesnt care about most games, does lag/crash over some games like batman (they dont like windows 8 much :< ) and I noticed that in most floors, not all, that i get unusual amounts of lag. Not framey laggy either, but like mini disconnections. And I have a laptop that runs SK on low with no problems and its been bothering me as to why this PC would be having an hard time.
