Test bed

We use Zero HD 2600XT in 3DMark05,  and use Sapphire HD3850 in the other three games.

There is no improvement in most of the test items.

AMD said Catalyst 7.12 will have about 5% performance boost in Company of Heroes which we did not notice that at all.  But World in Confilct surprise us, there is a huge improvement, boosting about 57% comparing to Catalyst 7.11.
