I have an office Pentium D PC that i have to use for work, and it is .. very slow. The only "enhancement" i can to it is perhaps to install an SSD for use as its primary drive. May i know if this can considerably speed up the whole machine as a whole?

This is a developer machine running eclipse, browsers, windows XP and some toad clients.

Yes, adding an SSD to an older PC often makes sense. The 'long' waits in desktop computing often come down to disk I/O -- for example booting Windows, launching Virtual Machines, compiling code.

Tom's Hardware recently had an article about just this: "Could An SSD Be The Best Upgrade For Your Old PC?", which I think you should read.

However, I would not invest a dime in a Pentium D (Intel Pentium 4 / "Netburst" derived architecture). That CPU is simply too slow.

Coincidentally Tom's also recently had a good article in which old and new CPU cores are normalized to the same frequency, to illustrate the Instructions Per Cycle differences. See the summary table here -- any P4 based PC is simply not worth investing in; a modern ~100$ Core i3 CPU will run circles around it. With both CPU's clocked at 3 GHz the P4 based CPU finishes their full benchmark suite in about 4 hours, while the modern "Sandy Bridge" based CPU only needs ~1½ hours.

Hi Jesper, i really can't upgrade the CPU for my case. Should i still consider an SSD upgrade for my case? –  Chin Boon Aug 6 '11 at 13:41
    
My personal answer is no; get a new PC, even if cash is somewhat short. See above; and read the Tom's articles to see why. Only you can decide what's right in your situation... –  Jesper Mortensen Aug 6 '11 at 13:48
    
Just don't use solid states with Windows XP. They are unsupported. –  Amicable Apr 5 '13 at 13:10

Yes it will speed it up. Probably a fair bit.

Is it the best thing you can do to speed it up? Maybe, maybe not. What's the constraint that you hit most often? Disk, memory or CPU?

I have installed 3GB of ram on the machine. It hangs at least once a day, i am guessing the symptom may be due to paging to the disk. Will it actually speed it up 30% in average cases? In my case where i use it to do Java development, running weblogic server 8.1? –  Chin Boon Aug 6 '11 at 13:25

@Chin: When you say "it hangs", do you mean it locks up / blue screens/ reboots? If so it sounds like a fault, and I doubt an SSD will fix it. –  Daniel Lawson Aug 11 '11 at 1:42
    
What Daniel said. Plus, instead of guessing, use the performance monitors to figure it out. –  MikeyB Aug 11 '11 at 2:37
