What do I *need* Catalyst Control Center for?

If you plan to OC you'll "need" that +20% power slider. Other than that the profiles are nice if you need them.
I use MSI Afterburner to set my voltage to 1.2v, do I really need Power Tune still?

Yupper. If you don't set it to +20% your card will throttle down. I sure wish the other utilities would find a way to duplicate that setting. If not for that +20% I'd never use the "overdrive" tab at all.
I just ran Furmark and at no point did my voltages or clocks throttle with Powertune NOT used. I'm OC'ing and setting voltage through Afterburner.
Only furmark will be throttled. Otherwise, you will only be throttled if you exceed 100C gpu temp.

I'm wondering if the +20% slider setting is saved in the registry somewhere...
If so, you could backup the registry, change the slider position and save that change, backup the registry again, compare the 2 files to find the difference, extract that registry key, then create a .reg file to make that setting without using CCC
I've been using AMD products since the launch of HD5870.
CCC always made games look worst or decreased performance. Even now with my HD7970 it only made things worst so I dont use it. Also, it drains some system resources (CPU and RAM usage). I guess u only "need" CCC if you have Xfire setup and need the CAP profiles.
And yes, MSI Afterburner saves the day.

Maybe I'm just phrasing it incorrectly. The "throttling" would be due to a lower TDP... From the [H] 7970 OC article:
AMD Radeon HD 7970 Overclocking Performance Review
Correct, it's throttling to hit a target TDP, but the way it achieves that target TDP is by dynamically lowering clock speed, which MrFace ought to see happening in Afterburner...Or he's just very lucky and his card ignores powertune for some reason!
Here's a couple screens of what my card does with powertune +20 (Left) and powertune +0 (Right):
In my own experience, it can also depend on what you're playing...benchmarks that try to test only 1 aspect of a card at a time (shader ops, fill-rate, raster ops ect) don't necessarily cause powertune to kick in. I've never specifically tested various games with different powertune settings, but I would expect a game that stresses (or is bottle-necked by) one aspect of a card's performance far more than others would behave similarly.
I am useing 12% and then max the sliders to the right "mine max at 840/1325"
Fan speed i left alone.
10% gave me problems every now and then when gaming for more than 3 hrs at a time i had random crash to desk top.

I do not see this at all. I run Furmark, BF3, 3DMark 2011...even with 1.275v and 950 core I do not ever see my GPU core throttling like your screen shot. Weird.
In my experience with my 6950's unlocked and OC'd, only Furnark would throttle my card(s). I ran clocks up to 950/1450@~1.25v. Games ran fine but Furmark throttled. Stupid Furmark.
I haven't had any throttling yet with my 7970 running 1200/1600 either, haven't played Furmark yet lol.

You can do that much better with RadeonPro.
That's what I thought(and have proven through numerous tests), but there seems to be a lot of FUD floating around that CCC is needed even with Afterburner.
W 8GB of ram, how much could it really drain?
If you dont need CCC, but you use Afterburner, arent you just switching one for another as far as resource usage goes?
