Apps like Abrowser could be part of the problem with so little RAM. But I'm afraid the movie to USB stick thing is actually GNU/Linux's excellence - You can tie up almost any GNU/Linux machine with the right amount of disk copy. I/O is so efficient it runs *fast* and consumes noticeable resources. But RAM yes the old trick with a computer for everyday rather than games use was to favour spending on RAM over CPU speed - because RAM was the most significant constraint. A 512Mb machine would fit with the size of computers when that was the advice. So add as much as it will take would be the plan for yours, it's relatively cheap. Specialists like mrmemory.co.uk often know the right ram and max it will take for a given machine (use their website to find out without buying). Search Youtube for a video of how to fit it, if that fails a blog/web search should turn something up. The nVidia point was sometimes the free driver doesn't have proper GPU clock control - with either newish or very old. So your nVidia GPU could be running a lot slower than it can. However, I haven't checked for your model and it's not a laggy screen all the time which would be the symptom you've complained of.
