Using cgminer & mining with 1 sapphire 7970

Just looking for input on my latest config file, is there anything you'd change? Like using more threads or whatnot, trying to put this card to work!

Code:

{
"pools" : [
	{
		"url" : "http://pool.abcpool.co:8332",
		"user" : "xxxxx.1",
		"pass" : "x"
	},

        {
		"url" : "http://mine2.btcguild.com:8332",
		"user" : "xxxxx_xxxxx_1",
		"pass" : ""
	}	
],

I don't have experience with 7970s but I dobut vector 1, worksize 64 is optimal?

No longpoll?  That sure as hell can't be optimal right?

Code:

"gpu-engine" : "0-0",
"gpu-memclock" : "0",
"gpu-memdiff" : "0",
"gpu-powertune" : "0",
"gpu-vddc" : "0.000"

I would either set these or remove them to avoid possible bugs in future versions.

Im getting a mhash/s of 670 so im not complaining, I figure i can only utilize its max speed to around 700

as to the longpole its getting turned off with my 2 pools trying to be load balanced /: the vector and work size seem to have configured them self
