Hey it's normally easier (at least in my opinion) to point your .bat file to a conf file which contains all of the settings for your cards. This is how I have mine setup, the .bat file contains the following:
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1

cgminer -c litecoin.conf
_________
Where litecoin.conf is a new text file I have saved (This is mining for litecoin instead of bitcoin, but you set this up the same regardless. Inside of this conf notepad file you can then include all of your settings, such as the following (which I am using a 7970, you'll probably want to lower your core/mem speeds to 1100/1300):

{
"expiry" : "120",
"log" : "5",
"pools" : [
   {
      "url" : "%http://stratum.pool.com:3334%",
      "user" : "%account:worker%",
      "pass" : "%password%"
   }
]
,
"scrypt" : true,
"kernel" : "scrypt",
"no-restart" : true,
"no-submit-stale" : true,
"remove-disabled" : true,
 
"queue" : "1",

I hope this helps, good luck!
