Re: Should I change my graphic card? 2005-05-19 - By pmiinalainen

Dear Tina and everyone else considering upgrades for their graphics
cards,
modern pc computers have endless combination of components,
operating system versions and patches, drivers etc. It is next to
impossible to get a 3d card that solves all your problems.
There are certified setups available from IBM, HP etc, but the
certification is valid if you use the driver versions they provide
and the programs they certify for (maya, xsi, 3ds max and avid video
editing applications and lots of CAD programs). If you install a new
dirextX version from windows update to get a quak XYZ game/
messenger/ office application /whatever to work, you'll loose the
certified qualification and free support. Those setups are for
serious business only. You basically do only one thing with those
workstation - 3D. No word, no e-mail. I know for a fact, that many
companies have nothing else installed there. Users have other
computers for daily office tasks.
I used to have such a workstation, installing microsoft office
caused it to crash as it updated some .dll that was used for windows
user interface components or something.... The workstation had to be
reverted back to factory settings ( format c: etc...)
Getting a new and faster graphics card can actually cause you more
troubles. They draw a lot of current (especially some nvidia models)
and if your power supply isn't really strong, the motherboard can't
supply enough current for memory, processing unit and graphics card
simultaneously and your computer will malfunction. When you are
upgrading old computer, you'll have to remember that some parts of
it may not live up to standards of today.
If you can afford, get a brand new computer. Install what you need,
one program at a time. Make restoration points after each install.
Test with large and demanding tasks. �nstall next application etc.
After everything works make a restoration point. Make a backup.
Never install anything if it works. If new graphics driver promises
to fix something in game xyz or to improve speed by 20%, don't
install it. It uses some hack to improve speed and causes you
nothing but trouble. If it tells that it fixes problems with carrara
studio version that you are using, don't install it unless you are
having problems described.
USe your old computer for e-mail and dull stuff like office
applications. Play games with that computer and never install any
games or funny or cute lite apps on the WORKstation. By skipping a
few fps of speed in newer driver, you'll propably get much more
stable environment.

ps. if getting a new pc computer, get an athlon 64x2 dual-core
processor. Dual core pentiums suffer from shared memory bandwidth
problems due to architectural differences.

3D art and design programs. I think you have to spend at least 300
to get a good card and I have never done that yet. What video cards
do you (all Carrar users on this site) have? I don't even think the
Nvidia GeForce FX 5200 is even Open GL, but of course I could be
wrong. Tina
