A couple of
months back a friend asked me my opinion on buying a new computer or upgrading
his.
The computer he had was over five years old. This means that the
technology had moved on. Not just the processor, but the USB, the hard drive,
the CD ROM drive, the memory. Actually the only thing that had not changed was
the case and if you looked at cases over five years old you would say that the
case is also outdated.
Now there are parts of a computer that are over five years old that are still
serviceable, actually as long as the component is still functional and not
having problems then why upgrade or buy a new one?
One consideration is the newer Operating Systems may not run on an older
processor, or there may not be enough storage on the hard drive. Then again you
may want to use the latest and greatest software and your video card doesn't
have the resolution or the manufacture hasn't written the drivers for the new
software.
Some of this is built in obsolescence, that is the manufacture stops
supporting products after a length of time because there aren't that many of the
product left in service or it is too costly to keep writing the software to make
the product work with newer programs or even newer hardware.
What it comes down to is what do you use the computer for and how much you
can afford.
Example 1:
In 1995 I bought two Antex tower cases, one for my main computer and one for
my server. Last year I decided to upgrade from a Pentium 4 to the Core 2 Intel
processor. When I decided to do this I priced out the cost of a new computer vs
the upgrade I did. By using my existing parts and only upgrading the
motherboard, processor, memory, and video card I moved from the P4 to Core 2
Quad with 4 gig of memory, a higher resolution video card with more memory for
less than $500. To purchase my computer pre manufactured would have been close
to $1400, and I would have a spare computer that I know I would have to upgrade
just because it was sitting there! :)
Example 2:
As my friend said, he wanted the latest and greatest and would I do the deed?
So I wrote up the spec's for a new mother board that would support Core 2 Quad,
4 Gig of memory, new case, 120 Gig hard drive, DVD rewritable drive, high
resolution video card with 512 meg of memory, two extra fans, and wireless
keyboard and mouse combo. The cost for parts came to just under $600, add to
that either my time to build the computer and the license for Vista and it comes
to just over $900 with out any tax, take my time away and it comes to just under
$700. A comparable pre manufactured computer comes in at $1200 but has a
one year manufactures warranty. The warranty is a mute point because each part I
would order also has a one year manufactures warranty. Where the break point
comes is when you build your own you have a choice of parts (quality over
quantity) and your upgrade path is wide open, not proprietary such as a Dell,
HP, or other manufacture's product.
So which way would you go?
Well you need to take a some facts in to consideration -
Is your current computer a proprietary manufactured computer such as a Dell,
HP or one of the other manufactures? If so the upgrade for these may only be -
a faster processor
bigger hard drive
and/or more memory
Some of the newer proprietary computers don't have the facility to add a PCIx
or PCIe video card or even a PCIx sound card it may only have PCI slots and will
limit what your choices are.
If the computer is a custom computer (what used to be called a clone) that
the architecture of the case and motherboard allows for upgrades you will save
yourself some money, sometimes a lot of money as in example 1 above.
Lets assume that your computer is a custom computer what can you do with it?
A lot, these are the items that should be upgradeable -
Motherboard
Processor
Memory
Storage
Video (card or embedded*)
Sound device (card or embedded*)
Power supply
Fan(s)
And then don't forget to think about your external peripherals -
Web Cam
Backup external drive
Keyboard
Mouse
Monitor
Scanner
As always research your parts for the best price but don't forget the
Quality, after all that is why you do it yourself, more bang for yer buck!
*Embedded is a device that is on the motherboard, a lot of newer motherboards
have all the peripherals on the motherboard as what are called 'chip sets'.
These embedded devices can be -
Network
Wireless
Wired (some motherboards have two NIC's now)
Video
Sound
USB
Firewire
If you want to upgrade one or more of these devices they can be disabled in
the BIOS settings and then you add your upgrade to the motherboard by using one
of the slots on the motherboard. Or you can have two devices such as sound
cards, I use the embedded sound device on my ASUS motherboard for gaming and
streaming radio broadcasts. Then I have an old SoundBlaster for my voice card,
this way I can listen to streaming radio and use my voice card at the same time,
neat.
