One thing I might suggest is going to sites like.
www.tomshardware.com
www.anandtech.com
http://www.sharkyextreme.com/
and a view others of this variety.
They will have articles about building computers.
Some will have monthly build articles.
Sharky's often has high end to value gaming rigs where the look at the best
price point or performance point in a budget.
But this is getting off base with your question, Other than they will have
reviews, guides and explanations about hardware. May take a few reads to get
a better understanding, but you should get there.
But on the subject of memory. I think some of the posts have brought up the
differences between celeron and P4 processors with respects to memory that
will be confusing.
Most processing devices in a computer has built in memory: ram, cache, flash
and hard drives. These are all different type of "memory". Some is long term
and others is short term. Some are replaceable others are fixed.
The CPUs will have caches built into them. One difference between Celeron
and P4 will be these caches. Their size and design respective of the board.
Why? Cost. More cache equals more cost for the CPS production. So for some
speed isn't as big an issue as cost. Thus Celeron and P4. However speed
oftern required more power, and is the other reason for the celeron
(especially in notebooks computers.).
The thing to know about cpu cache is that it is fixed. Only way to increase
it is to replace the CPU (at least for mere mortals.).
But to replace the CPU may mean replacing the motherboard and ram. Basically
rebuilding the computers.
Know that different celeron cpus are not interchangable with your existing
motherboard.
On another subject of memory, with respects to windows. Their is "virtual"
and ram.
Virtual is the area on your hard drive the OS temporarily store information
during its operation. Generally you want at least 2gb of HD space for this
process, plus an additional 15% open for defragging the hard drive. (in case
you were concerned about hd performance issues). Fragmentation, open space
and hard drive speed will have marginal impact on your rg.
The other memory is the RAM. Now it is my understanding that most Desktop 32
Bit Windows OS's have a limit for practical use of 2gb of ram. This until you
get into 64 bit CPU's.
Then there is the issue of the speed of this ram and its type.
Here I suggest going to the links above and reading the guides.
I think after reading those sites you will begin to understand the number of
variable that goes into determining performance. And we have not even begun
to talk about compatability issues really. Such as power supplies, demands of
the devices. ATA versus SATA, etc. drive speeds, etc.
In the end, there is a practical limit of what you can do to increase the
performance of any machine. Practical meaning either the physical limitations
or money. Often is the case it may be more practical to replace the system
than it is to rebuild and existing one.
hopefully this helps you a little bit.
