Ackmed, We are making the CPU the bottleneck to make sure its the drivers using the 2nd core thats increasing the performance and not general driver optimizations. Plus, all my benches were run at 1024x768 not 640x480 as you supposed.
I do NOT know how to bench BF2 at the moment or KOTOR or any of those 'other' games. So, what I posted, is the best I can do at the moment. Sorry it doesn't meet your standards. I just did what I was able to do at that moment.

To whoever was wondering earlier about eh 50% up to 70% cpu usage I try to explain alittle below 
When I mentioned 50% or so with the 77.72 and 78.01 drivers and then 70% with the 81.26 drivers, that is the TOTAL system usage. That is the balance between the total of both cores.
So, the 77.72 and 78.01 drivers were definitely NOT using he 2nd core to do much of anything while playing the games since the total system usage was only 50% or so which would be the performance of 1x core.
BUT, 81.26 drivers DOES show that they aRE using up to 20% of the 2nd core to do some type of rendering.
Sorry if I don't make sense 

  Maybe I will try later.
