I have recently built a new computer completely from scratch... and I can't understand why I am having problems running 2 WoW accounts. This computer IMO should be able to tear up 2 WoW accounts with ease. Well let me give you the details.

*COOLER MASTER Real Power Pro RS-C50-EMBA-D2 1250W ATX Form Factor 12V V2.3

*COOLER MASTER HAF 932 RC-932-KKN1-GP Black Steel ATX Full Tower Computer Case
*CORSAIR Dominator GT 6GB (3 x 2GB) 240-Pin DDR3 SDRAM DDR3 2000 (PC3 16000) Triple Channel Kit
