This +100SSD sees the biggest bang for the buck IMO. Night and day difference.
Are you running Windows, if so which version? Make sure to clean up the temporary files as well and cleanup the start up tasks etc. All that windows garbage slows down computers as well.i have an old HP laptop 4540 . its got 4gb ram and a 500gb disk in it. i want to speed it up a little but don't want to invest too much. budget is $50 . So what would give me better performance, ram or a SSD? it takes a while for it to boot up
