Thank you both for your advice.
Yes, many questions abound. I have a 1.0 GHz Athlon system with 512
MB of RAM and a decent (but not high end) GeForce graphics card.
You will likely need a new power supply if upgrading all the
major bits, new board/CPU/video, unless your present has an
atypically high 12V current rating and your replacement
video isn't very power hungry.
My
system is perfectly adequate right now for my needs, but when and if I
upgrade to Vista when it comes out, I might need some extra
horsepower.
Do you feel compelled to upgrade to Vista? Given a choice
I'd upgrade the system and stick with XP, before I'd upgrade
to Vista and (upgrade same system moderately or even replace
with the newer system). Vista will have bugs, learning
curve, and suck performance out of any box. A new system
right now would seem reasonably faster to you, but if you
wanted to do it when vista comes out, you might be
essentially standing still performance-wise, unless you have
particular tasks that you know will benefit (but none
mentioned so it's an unknown variable... I presumed you
didn't have very demanding tasks else the system upgrade for
performance reasons would have already been more important
an issue pre-Vista).
My other components are fine (DVD drive, CD burner,
monitor, etc.). I just figured that upgrading they key parts would be
more feasible than buying a whole new computer. Of course, it would
be nice to put THIS machine in the living room, and then have a brand
new system as my main machine here in my office/bedroom.
Keep in mind, Vista isn't here yet, by that time you may
have your optical drives wearing out or simply getting too
dusty for best operation, and if your hard drive is same age
as rest of system, it's expected lifespan may be about up.
If your uses aren't demanding, a new hard drive might be the
best performance boost right now.
But Windows XP runs fine on my current setup. Oh, Microsoft -- why oh
why must you insist that we relegate our current machines to the trash
bin when you release a new OS?
Well they do like to sell license to OEMs for bundling with
new systems. Unless someone puts a gun to your head though,
I don't know if it's really so important to move to Vista.
What is it your present system can't do, that you hoped to
gain? It might be premature to presume Vista will be more
useful for common tasks, but perhaps more limiting if it's
DRMed so much the same old things don't work as they did.
