Summed up, I would suggest that you try these settings:

<coproc>
<type>ATI</type>
<count>0.5</count>
</coproc>
<cmdline>w1.15</cmdline>

To save a a bit on the power consumption, you can reduce the memory frequency, as MW doesn't use a lot. You have to see how important this aspect is for you, but going down to 600MHz or so shouldn't show much of a difference to the runtimes. When you go further to let's say 300MHz (if your card can run that stable), you will start to loose a few seconds calculation time. But you could compensate that with a raised GPU core clock of course ;)
