If you select steppings G1/G2 and then pull down the model list, you can see the range of processors in each stepping. I don't think any of them are quad/triple cores. Searching the "3800+" and knowing it is 65 watts (EE) shows either an F2 or F3. Likewise, the "4850e" is a G2. Checking the cpuinfo on systems using a 4850e (G2) and a 4600+ EE (F2) both give "cpu family: 15", so they have included the Gs in the excluded group, too. Steve
