Is it more than 1.5ghz ?
If so, give it enough ram, turn off all the snarking window animations, shovel out all the startup-vampires with 'msconfig', uninstall norton (don't even MENTION vista) and then it will do for most workday tasks.
I must admit to being pretty baffled already about Intel CPU's, the 'Dual Core' vs 'Core 2 Duo' thing took me months to get a grip on. This new star rating wossit looks set to increase rather than decrease my bafflement.
Am just getting too old to give a shit ?, or too stupid ?, or did processors get good enough about 5 years ago to not be of interest any more ? Wouldn't it run better with an extra gig'o'ram instead ?
If you araldite a plastic handle to the die of a pentium pro 200 it makes an excellent dog-brush.
