What you need to know about
Buying a Computer
Usage
So many times we have come across clients
who have super computers and all they do is check email.
If you have the money then more power to you. But for
those of us who live in the real world… come on. If
you plan on doing heavy graphics or video processing
or even high end games, that $400 computer will not
do. If you want to write documents and send email, by
all means enjoy. Figure out what you want to use the
computer for and then buy accordingly. Below I will
list the basic most important parts of a computer and
tell you what they are good for. After that I will give
you my recommendations in terms of specs.
Specs
-
CPU – better known as the processor.
All you graphic artists, video editors, web designers
and power users need a good CPU. There are 2 brands,
Intel and AMD. AMD is best suited for gamers and that’s
it. Intel however offers 2 types of processors, the
Pentium and the Celeron. If you are that power user
I mentioned above, go with the Pentium class. If you
are the document writer / email checker, that Celeron
will suit you fine and you will save big bucks with
the Celeron. What’s the difference between a Pentium
4 3.0 GHz and a Pentium 4 3.4 GHz? Unless you yourself
are a computer, the only difference is money. No need
to spend such drastic amounts of cash for a few hundred
MHz. I promise you will not notice the difference,
except in your checkbook.
-
RAM – better known as memory. This
is the all important most performance changing option
you can control. All the latest programs require more
and more memory to run better. And the new software
that, just like computers, is upgraded every year
will require more memory to run efficiently. The fact
is this; the more you have the better your computer
will run. Up to a point that is… we’ll talk about
bottlenecks a further bit down. My personal bare minimum
amount of RAM is 256 MB. Anything less than this is
substandard and you will suffer performance degradation.
Spend the money on memory. Does that mean you need
2 GB of super high speed DDR RAM? That again goes
back to your usage. If you’re that power user or gamer
I mentioned before, you can never have too much. If
not, 256 – 512 MB is more than enough.
-
Hard Drives – The hard drive is
often confused with memory. The hard drive is used
to store programs and files. Memory is used to LOAD
programs and files for the processor to use. With
that said, what’s so important about your hard drive?
Well, we all know that hard drives are getting bigger
and bigger. I remember my 40 MB hard drive way back
when. And now hard drives are in the 200+ GB. However,
there are still 3 main classes of hard drives when
dealing with computers. SCSI and IDE (5400 rpm and
7200 rpm). SCSI hard drives are very fast and definitely
more expensive. But their speeds far exceed those
of regular IDE hard drives. When buying a computer,
a lot of people don’t notice that the “$400 computer”
hard drive they are buying is actually a 5400 rpm
hard drive. What’s the difference between 5400 and
7200? Everything. Those numbers represent the number
of revolutions the disk will make in a minute. Just
like a car, the higher the rpm, the faster you go.
Same exact concept. I personally recommend a 7200
rpm drive to any computer user regardless of their
usage. If you really want Hard Drive speed to be a
non issue and have the best “engine”, SCSI drives
are for you.
Of course, as with all things, everything
will eventually fail and break. Contact Miami

recovery and what you can do to prevent data loss.
-
Video Card – Once again, if you
are that power user you definitely want a good video
card. Document writers / email checkers – you don’t
need a great video card. Even today’s standard video
card is more than enough. The biggest mistake people
make about their video card falls back to their usage
and bottlenecks. We’ll discuss bottlenecks in a moment.
Some video cards are made specifically to be great
cards for games, others for video editing and graphics
or a combination. Which video card do you need? The
one that offers the best compatibility to what you
are using it for. A lot of computer games have glitches
with different video cards. If you want compatibility
and performance, Nvidia and ATI are the way to go.
-
Everything Else – There are still
many different components in a computer. The above
mentioned are the most important. And unless you are
building your computer from scratch (not recommended
unless you know what your doing and getting into)
these components are pretty much standard.
-
Bottlenecks – Simply said. What
good is a super fast Processor if you have a Pinto
for an engine (5400 rpm hard drive)? What good is
all that super high speed memory if your processor
is chugging along to keep up? There are always bottlenecks
in a computer. The key is to balance everything out
to what you’re going to use it for. Below I have 3
system specs laid out for you as I recommend them.

Where to Buy - Great question.
Buy from a reputable dealer. Direct from the manufacturer
if you can. Be careful of giant computer stores who
are always trying to get rid of their old merchandise.
I won’t name any names, but many of these stores and
individuals sell computers that are outdated already.
Not only that, but they are also usually very limited
in the configurations you can buy the computer in.
Not to mention that they are being pushed into selling
what’s good for them and not good for you. These people
are not your friends, they are salesmen. And salesmen
will always try to get rid of what they have too much
of to make room for the new merchandise that you should
be getting. Be informed and don’t let anyone push
you into making a purchase. Remember, the longer you
wait, the more you get for your money. Avoid building
a computer or having someone build one for you if
you can. The reason is that all the parts inside have
their warranties with multiple companies. What does
that mean to you? When you have a problem who are
you going to talk to? You’re not even sure what the
problem is. And, just like all things, each company
will blame the other and eventually you’ll have to
call Miami Computer Repair at 305-350-1953 and we’ll
solve your problems and cut through the tech support
red tape.
I hope this article helps you in your
quest to get the perfect computer. And remember, we
here at Miami Computer Repair are here to help. If there
