Not really a trick question. A valid question. The answer was 'Just
for ordinary apps'. Which doesn't answer the question anyway.
ordinary = surfing, e-mail, and games ?
or does ordinary = DVD ripping, MP3/video encoding, solid modelling
?
It all depends on what you are using it for. I don't know about
games, since I keep those away from my PC and use a console, but if
all use is for the internet ONLY, chances are a 1 GHz PIII will be
about as fast as the dual-core.
While a hundred different benchmarks may show a huge advantage to
the dual-core, in real life use, the user may not perceive as great
a performance difference.
The big question becomes, do you want to spend $65 on the P4/2.8GHz
CPU or $180 for the PentiumD 940.
