Best web browser for old computer

If you have a old computer like mine (1.6GHZ, 512 Memory & 30GB) & looking for a decent web browser. I strongly recommend Opera 11, this version is much faster than any modern browser, firefox 5, ie 9, google chrome even safari.

This was really surprised me yet after test all those browsers on my computer, Opera is the fastest web browser that I have tested.
