Fact:

My current setup

AMD Athlon 64 X2 Dual Core 6000+ 3.00GHz
8800 GT
3 GB of RAM (XP Max)
single SATAII drive 320GB

Is more than beefy enough to 5box wow, watch porn and fraps the main windows character at the same time without any noticeable drops in FPS. Main goes from 70 to 40 when activating fraps Not noticeable by human eye.(of course using horizontal span due to XP)

Alt windows are stuck at 15FPS all the time with keyclone command editor setups.
