@Tsurani: I'm not very current with Intel's chips, as I prefer AMD myself. Can't interchange AMD and Intel chips on the same board though. Last I was looking the Nforce 780 was a good board (don't know about the 780i though). Generally any dual-core over 2.5GHz should do you fine for almost anything.
@haylen2: Not polite to hijack someone's thread.
But... yes please post more detailed info when asking for help, but just a shot in the dark I will guess that your video drivers got toasted. If that's not the problem try the Repair.exe in the WoW folder in case something in WoW got corrupted. Major power surges like that can be devastating unfortunately. Suggest an awesome surge protector (with $100,000 warranty or more), or an UPS.
Hope that helps.
