Speeding up an older computer

[CloudWatcher]

6. Depends :)

It all depends on what's slowing down the machine. If it's low on memory, adding more RAM will be a big win, otherwise it'll be a waste of money. If it's waiting on disk I/O then replacing a spinning hard drive with a solid-state disk can make it fly. If you're waiting on the Internet (a slow ISP), then making your machine faster won't really be that noticable!

Depending on what the driver does, a driver update could help with RAM management, disk I/O, offload some computing to your graphics card or even help your Internet run a little faster.

Results will vary depending on what's slowing down your particular configuration / usage pattern.
