When my net disconnects, my computer grinds at 100% CPU usage where normally, 10 active WoWs, 9 active honorbuddys and a game of league of legends gets me at 80%.
My Comp specs:
i7-2600k @ 3.4ghz
12gb DDR3 Ram
2GB ATI 6970 graphics
128GB FS3 SSD
(Honorbuddy is on a RAID0 with two 1.5TB 7200rpm Western Digital Hard Drives).
