I have the above. Generally happy with the performance.
However in the future I'd like a Turion of some sort.
The ML34 sounds decent at 1.8 GHz and 1Mb cache.
However I don't think it'll be a huge performance increase over the
already 1.8GHz Sempron.
There won't be. You'll probably struggle to even notice the
difference. Not particularly worthwhile unless you've got a lot of
money burning a hole in your pocket.
What about an ML30 which is 'only' 1.6GHz (1Mb cache)?
Am I going backwards?
Some applications will probably be faster on your Sempron, some will
be faster on the Turion ML30. Either way it's definitely not a
worthwhile upgrade.
Really, even the top-end Turion ML-37 (highest processor listed as
being supported by your Compaq V2000z laptop), at 2.0GHz and 1MB of L2
cache, is probably not going to be a noticeable upgrade most of the
time, just not worth the money unless you're really desperate for a
small extra boost. Going from 1.8GHz/128KB of cache up to 2.0GHz/1MB
of cache is probably going to get you between a 20 and 30% boost in
performance. Now consider that a 20% boost in performance is about
the minimum you're likely to notice in day-to-day use, this really
doesn't work out to a very substantial upgrade, especially not with
the ~$250 price tag.
There are two things that you could do that might improve the
performance of your system though. First, upgrading your memory to
1GB if you don't already have as much. If you're applications are
really memory hungry then 2GB (most the laptop will support at this
time) might be worthwhile. The second upgrade would be to get a
5400rpm or even a 7200rpm hard drive for that laptop. If you
currently have a 4200rpm/2MB cache (or even 5400rpm/2MB cache) drive,
as is common on this system, then the upgrade to a 7200rpm/8MB cache
hard drive is probably going to be more noticeable than going from
your Sempron 3000+ 1.8GHz/128KB chip to a Turion ML-37 2.0GHz/1MB
chip. Where the processor upgrade will cost you ~$250, the hard drive
upgrade might cost you half as much.
