BAMT 0.50c 58xx 59xx Cards, stock phoenix?

[cooler-persistence]

I'm running rigs on BAMT with 58xx 59xx Cards.  Stock drivers.

Would upgrading drivers and/or moving to cgminer make a performance difference?
If I did cgminer then does it make a performance difference to run the latest stable version 3.1?

I appreciate any tips, I've been running a while but looking to optimize as much as possible.

To confirm, new cgminer will not make much of a difference right?

I'm running BAMT on one computer with cgminer 2.11.4 and catalyst 11.6.  I had this 7950 gpu in my other computer originally running cgminer 3.1.1 and catalyst 13.4.  I saw no difference in hash rate when I moved the card to the second computer.

That is just my experience though and I haven't played around much with different drivers and cgminer versions.

Upgrading drivers and SDK for your 5xxx cards, no.
Moving to a recent cgminer, yes, although not spectacular.
