I've this log and as could see there are two GPU but can't get working both of them (I do like to do it without crossfire):

Any Clue about ??

You need a cc_config.xml (http://boinc.berkeley.edu/wiki/Client_configuration) with at least:
<cc_config>
<options>
<use_all_gpus>1</use_all_gpus>
</options>
</cc_config>
By default BOINC only uses the most capable of two GPUs of the same brand.

Yep, Boinc will only use the most capable GPU by default, you'll need to enable <use_all_gpus> by making the following cc_config.xml dropping it in your Boinc Data directory and restarting Boinc:
<cc_config>
<options>
<use_all_gpus>1</use_all_gpus>
</options>
</cc_config>
If you're done it right you should have the following in your Boinc startup log:
08/01/2013 22:28:46 Config: use all coprocessors

So if I have a 7660G + 7670M, boinc will use the discrete card (7670M) over the integrated one every time?
It's a nice feature (fail safe). Until they figure out how to manage every Compute Unit :)

Ok done after deleting old cc_config.xml that don't know the reason don't allow me to do it, now working with both GPU but only crunching with 3 Cores instead of 4 ?? :'(
pd.: thanks a lot all of you for your support.

my fault how could be crunching with four cores when GPU work is 0,8 CPU + 1 GPU in two same instances there should be at least one core lost to feed the GPU applications.
