My new desktop arrived last week from M-Tech. Intel i7-930 processor, triple threaded RAM - 3 4gB DIMMS. I don't have formal testing capabilty but I have to say that Dragon is much faster. On my old PC there was a noticable slowing when I moved the slider toward Accuracy away from Speed. Now with the slider all the way to Accuracy it is still faster than I ever saw before. Can't believe how nice it is not to wait to see the words appear.
