Spyware and virus could be an issue, worthwhile to check regardless of whether it's affecting your performance or not.
Secondly, what OS are you running? If it's Windows XP home or pro, which I suspect, 512 is realistically the minimum you should be using to run most things adequately, even though the specs for XP are much less.
Thirdly, open up your task manager and determine how much physical memory you have available when you are typically using your computer. ie when you notice it's slowing down, use the task manager to view how much free memory is available
If you have anything less than 64 MB free, you are definitely in a situation where more memory would help you out. As you run out of RAM for use by processes, your computer starts to copy things out of memory to the page file, this causes slow downs due to the transfer of data from the page file, which resides on your hard drive, is much slower than accessing the data directly stored in RAM.
Also, while you have the task manager up, make sure that none of your processes are ramping up your processor usage. You can check the proc usage and see if any processes are hogging it and causing bottlenecks at the CPU.
I would say unless you are getting a markedly faster performing HD or your old one was having physical issues hampering performance, you prolly won't see much of a difference by simply replacing the drive and copying over the image. Defragging regularly can greatly enhance your drive's performance since it takes less time for it to find data it's looking for on the drive. That and more RAM is most likely your two best and most cost effective ways to increase performance.
