I am looking at upgrading to a new PC. I knew where I was with AMD.
AM, AM2, AM3. Simple but with Intel it is as confusing as trying to
get the best deal on a mobile phone.
Atom, Core 2, Pentium M, Itanium, Xeon, Pentium 4 and now i7. It's
enough to give you a head ache and I haven’t looked at DDR2 and DDR3
Still not sure why I would need 4 cores as it doesn’t make most PC 4
times faster. Would 4 Ford Fusion cars make me a Ferrari?
What do you have now for a computer ?
(Number of cores, clock speed, other parameters)
What kind of programs do you run ?
(games, MS Office, video editing, photoshop...)
Is your current computer too slow ?
Note that, on a modern system, you can improve things two ways.
Faster CPU. Or faster hard drive (SSD, for lightning fast file access).
Some of each in the new machine, will make the upgrade feel worthwhile.
(550MB/sec on a SATA III port - 50,000 IOPS, never defrag again
)

In terms of clock rate, depending on what you already own,
you might not be exactly blown away by the new system. If you
had a 3GHz Core2 and moved to a 3.6GHz newer processor, yes,
it's faster, but you need a stopwatch to tell the difference.
Where the difference would really show up, is video editing
or Photoshop, and to a lesser extend in gaming (really depends
on the game). On some older programs, maybe the difference
wouldn't be as noticeable.
To see whether a quad core is the right answer, you have to
look at the mix of programs and which program you use
the most.
There are benchmarks here, but they're multithreaded (behave
like a video editor or Photoshop). Getting good single threaded
comparisons is more difficult, but as far as I'm concerned,
is still important to include when benchmarking these things.
The single threaded benchmark comparison, is to show a pathological
case, where the new CPU isn't used to its maximum, and then,
what the resulting speedup will seem like. I think it is good
to know that. On the one hand, we know a 3.6GHz processor is
3.6/3.0 faster than a 3.0GHz processor, but with each generation,
there are tweaks to the processor that affect the IPC (instructions
per clock). That could account for another 10% more perhaps.
And something like SuperPI, can give you a feeling for that.
