Hey wanna, FWIW I just got a new ssd for my ID classic, and put MC with Win7 on it.
Needed live input, like you.
The 2820 celeron is pleasantly surprising by live-streaming with 8 channels of convolution.
6 x 65,536 taps; 2 x 256 taps; 48kHz
DspStudio performance says 3.5-4 X real time; task manager says CPU about 25-30% with peaks into low/mid 40's
It's working great
