The bottom line
It's pretty clear from these basic tests that Internet Explorer 8 has a long way to go if it is to catch up with Firefox 3.0 in terms of JavaScript performance and CSS web standard compliance [UPDATE: Whoops, I meant web standards compliance, not CSS, I was still thinking in ACID 2 mode ...].
However, I think that it is worth pointing out that when it comes to performance, Internet Explorer 8 Beta 2 is three times faster than the Internet Explorer 7. ACID 3 compliance however isn't much better than that offered by Internet Explorer 7.
IE8b2 report card: C- ... Could do better, much better.
