OC'ing XFX 6950 1GB using afterburner, do I really need powertune 20%?

Hey peeps,

So I started tweaking my non-reference XFX 6950 1GB and to my luck I could implement voltage control through MSI AB which is surprising since its non-reference. Anyway, the card went to 930/1300 at stock voltage and is now sitting at 970/1300 at 1.188 vcore. I've been hearing about OC'ed cards throttling specially when OC'ed in order to maintain their TDP envelope and I don't want that to happen. Can I implement powertune without using overdrive? If not, can I use overdrive to ONLY implement powertune and AB for voltages and clocks? Will they play nice together??
