in addition to processor....RAM.....MOTHERBOARD(with their support to higher buss speed n DDR RAM)....HARDDISK(with reference to high speed reading n writing thus increasing application performance)

mattwood78,
That all depends on what benchmarks you are looking for. Are you talking about overall PC performance? In my opinion, it takes a blending of the right components to gain a higher performance level from a new PC. If you are referring to upgrading a component to gain performance, adding memory is a good place to start on an existing system without replacing the motherboard, which is also a performance boosting option. What exactly are you trying to improve regarding this system? You're question is a little vague :) Please elaborate.

Eye-catchers on the conference table

Challenge: The i-unit group was not satisfied with the audio quality during remote meetings. They were looking for a portable solution with excellent audio quality for use in their conference room but also at their client’s offices.

Nice response time guys! I think we all pretty much agree on this one :)

It also depends on what you are trying to accomplish.  If you need that spreadsheet crunched in the fastest time, you want to invest in Processor and memory.  If you are looking at network throughput, then your first thought would probably be the NIC.  If you have lots of people or an application hitting the hard drive, then you would want to concentrate on the hard drives and controller.....   As Imporve said, you need to blend the right components.  It makes no sense to put in a super fast processor and then criple the machine with 128mb of RAM, or use a UDMA 33 hard disk on a Disk intensive game., etc.

Having said all that, most people can get the biggest bang for the buck with RAM now a days.

It is also a bit circumstantial to what you use your PC for.. For example: If you're a gamer, you may notice a larger increase in performance if you were to get a new Graphics Card... Or, if you're a programmer, when it comes to compiling things, you may notice that it's faster with a better processor... Or for an internet user, getting a faster Internet service and Modem; But just to repeat the other guys ;) ... Probably in order:

  - CPU
  - RAM
  - Mobo
  - HDD
  - ..

User knowledge will also play a role in performance.

What do you want to perform better?

If you want to access data faster, enjoy faster boot times, load maps faster in games then you want a new Hard Drive.  If your motherboard supports it you want a Serial ATA drive.  If you cannot utalize a SATA drive through your motherboard directly then avoid the add in cards and get an ATA-133 drive that uses an IDE ribbon.

If your interested in just a general increase in everything you should look at a new motherboard/cpu for your system.  Usually the most costly of the upgrades because new generation equipment requires updated ram and case/psu parts before you can use it.  This choose will give you an edge up in speed that no other component can truly offer.  However choosing this route is basically building a new computer and it can be expensive if you don't choose to budget yourself.

Ram upgrades are the cheapest, easiest and most common upgrades because they offer huge speed increases compared to the difficulty of the upgrade.  Even the most novice computer junkie can install a RAM upgrade in a desktop or modern laptop, as todays systems are built with upgrade ease in mind.  Slide the new stick of ram into an empty slot or replace a smaller stick with a newer larger stick to increase your ram.  This upgrade increases how many applications you can run before a slowdown and it also helps systems launch applications faster.  Newer systems use fast DDR (double data rate) or DDR2 ram that can come in many varried speeds so be sure to buy the correct kind or it may be incompatible with your system.

Are you into gaming?  If you are then you probably want a new graphics card, this device will enhance your ability to play games by providing you with a dedicated faster more powerful GPU (graphics processing unit) designed to handles todays games.  The only restriction on upgrading one of these is how old your computer is and if its even worth upgrading.  There is no reason to put a $150 graphics card in a pentium 3 800mhz computer.  The computers processor is not going to handle todays games and therefore the upgrade would be futile.

CD/DVD Drives, if you enjoy ripping your cd or dvd's to the computer to watch later you will want to find fast drives with cd reads of at least 48x and dvd reads of 16x.  This can improve software installation times and also a 52x cdrw drive can burn an entire cd in 6minutes.

While not physical components you still must use caution with Antivirus solutions of today as they are also a big factor in speed.  Do not be suckered into a full norton 2005 system works suite just because of the brand.  The full suite of software is going to slow any computer down, more so the older systems will be the ones choking under the pressure.

Your Hard Drive has the largest impact on performance.
Even tho the interface speed is rated at 100mbps, or 150mbps... you're still only getting a sustained rate of 20 to 60MBps off the platters.  The hard drives typically don't live up to their interface speed by a long shot.  So, if you can go SCSI 10,000 rpm drives or better... you will see a huge performance boost... over typical consumer drives.

Aside from that...  changing to a faster disk system visually increases your performance.
Assuming we have a generous amount of RAM... putting in faster RAM or a slightly faster CPU... you probably won't notice a visual speed increase.  If you say go from an AMD 2000 to an AMD 2400+ it would be hard to notice a difference.

Every part has it's role of course... everything has to have a good performance... but if you look at your CPU utilization... the majority of time.. it is 99% idle.

There is no answer to your question as stated.

Consider a gamer:  To him, video performance is critical.  To anyone using Word or browsing the web, video performance is irrelevant.

Consdier someone doing database analysis:  To that user, dealing with possibly gigabytes of database in multiple files (some containing the data, some containing indexes into the data), Disk drive speed will be almost everything, because his software is spending most of it's time accessing the hard drive.

Consider someone browsing the web:  To that use, network speed will be most important.

Consider someone converting an AVI file to an MPEG for creation of a DVD.  It's almost totally CPU speed dependent, and can take more than 10 hours.  Aside from CPU speed, for that application, nothing else matters.

It's the working being done by the computer that determines which component of the computer is the bottleneck in overall system throughput.  And since you didn't tell us what you will be doing with the computer, we can't say what aspect of the system is most important.  It could be almost anything, depending on the application.
