Sorry, but I have to disagree respectfully. The increase in speed for chess from a Thunderbird-Athlon to a Barton-Athlon, or from 256 KB to 512KB was close to nothing. (For sure less than 3%) The rest is marketing. (OKOK, some Video-Hyper-Gaming-3D gadgets may be faster) > >Thanks for the info on the CPU cores, however. > >Dave Bye Ingo
