Unlocking a 6950 to a 6970 is only a small gain. Overclocking it is alot less hassle and has a higher chance of keeping your warranty.

Would you mind sharing another, more reliable calculator, or a reference that can empirically prove this statement?

I'm genuinely curious, as I build 20-30 systems a year for clients, and have been using this calculator to be 100% safe about the PSU choice. It takes into account capacitor aging since my clients will usually keep their system for 3 years on average, and accounts for 100% load to be safe.

Last thing I want is a client phoning saying his PC blew up while he was encoding his latest video for work.

100% off? that doesnt make sense.

But the calculator is off by a significant amount.

Under gaming stress I doubt he would go above 450 watt usage

Also, getting a 6950 != 6970. Unlocking shaders will give you a 3-5% performance at best, but the 6970 has faster memory and is overall a better card. For 275$, the 6970 is a no brainer.
The 6950 is basically a 6970 with disabled shaders, so why would the 6970 be so much better than an unlocked 6950. You get almost near identical performance out of an unlocked 6950 as opposed to a 6970, maybe 2-3%less overall, but for the price difference, its negligible.

Back OT: Actually thinking about it, after taxes and such they will be very close in price. But the warranty and such adds some value to the 6950 idea. But then again, if you can get the 6970 for $275 exactly, it would still be a very good deal. I just have a hard time saying go for it when the costs are almost the same but you can get new with warranty for slightly cheaper...

A good PSU is the backbone of any good build. You can skimp on a lot of things and get away with it most of the time, but you should NEVER skimp on a PSU, EVER. If that sucker goes down, it could take your whole system with it.

That said, you don't have to spend $100-$200 for a good PSU. Even something cheaper like a good OCZ (do your research, no matter what brand) can be had for very cheap these days. The ModXstream Pro series are always rock bottom priced with great quality and a modular design. I rely on those units a lot for budget builds and on lower end gaming solutions. Never had an issue from a buyer yet.

But this is not what I was measuring with the calculator. I was measuring wattage under 100% system stress and capacitor aging of approx. 20-30%, which equals to about 1 year of regular 24/7 use.

Like I said, very unlikely, but it's to be safe. A price difference between a good 850W and a 500W PSU is often less than 100$, when the complete system costs 1500$ and above.

I'm simply advocating on the side of safety, but would be very open to new documentation that exposes the calculator is completely unreliable.

This is true, but I was under the impression that the 6970 ran faster VRAM chips on tighter timings, which is why the 6970 has an 8 pin rather than 2 6 pins like the 6950?

Just wondering... which craigslist is this?

I posted mine up for $300 on craigslist the other day lol.

[edit]: Oh I see you're from the US and it's Sapphire. Nevermind.

Holy crap!
this part of OCN is VERY active! lolz
well looks like I got some great advise.

Thanks for your input guys. It is time to burn this 5550

New PSU+new 6950= Win! I'm thinking I can do this all for 350 ish and feel like I dont have to worry for 2 years or so if I add a second or third 6950.
And cant beat that warranty if i buy new.

getting my keys and going shopping WOOT!!! YAY for stimulus package!!!
