The way Kepler chips work makes voltage control kind of useless.

Mine is running at 1280/3300 max boost clocks on stock voltage but it refuses to go any higher regardless of how much voltage I feed it.

680 Lightning with LN2 bios is a bit different story however.

But then I read that almost all of the new boards that come out for the 7970 are voltage locked and you can pretty much kiss OC'ing goodbye." Now if I wanted to pony up another $60 bucks and maybe have a chance at overclocking - but at the risk of extremely high temps - I could have gone for a midrange 7970.

I'm not really concerned about the VRAM at this point, I only game on one monitor.

Edited: Specified type of 670 (PE)

You can OC a 7970 pretty far without touching the voltage at all. Mine go to 1250 on the core with stock voltage. Also, VRAM is not currently an issue, but someone here already made a very good point that PC game specifications are almost a direct product of the capabilities of console games, so now that new consoles have loads of VRAM, developers will write games to use loads of VRAM even at 1080p. I very much anticipate AAA titles to start showing this trend before the end of 2013. Remember when everybody said 1gb of VRAM was plenty for everything? That was only 2.5 years ago!

Someone else also pointed out that the 670 PE is actually a slower card with less value in every way than a 7970. The review you have looked at is VERY old, and 7970's perform much better now due to very good drivers from AMD (7970 is better than a 680 which is obviously better than a 670). Perhaps I just sound like another opinionated fanboy, (my rig is mostly AMD) but I strongly believe that the 7970 is a much stronger purchase than a 670.

While in the end the decision is yours and you should do what you want, just know that there is an absurd amount of unfounded AMD hate about drivers, quality control etc and having owned 5 AMD cards (5670, 5870m, 6990, and two 7970's) and built systems with at least a dozen more, I can say that not one has ever let me down. Just bear in mind when you read posts flaming AMD whether that person has actually experienced the issue they are saying exists, or whether they are just spreading false information. Oh boy, I'll stop preaching now. kthxbai.

I haven't used the MSI 670 PE, so I choose to be silent, but I couldn't stand that guy in this case.
And yet, I spent a little time "binging" to find out the MSI 670 PE at 1.2GHz barely beats a HD 7970 1GHz.
Even with the Voltage locked, you still can easily push the 7970 to 1.1GHz~1.15GHz or so to regain control.
Note that the 670 may exceed 1.3 or even reach 1.4GHz with its turbo core to barely beats 7970 1GHz.
I personally don't want the turbo mode at all, because it may cause unstable later.

I appreciate everyone input. I will receive the card on Monday and will consider utilizing the Newegg Standard VGA return policy if it's underwhelming.

Here's how I see it
~$400 gets you reference 7970 GHz which you can OC yourself
~$370 gets you factory OC'd 670 which you can also OC yourself

push both to its limits...assuming which ever can unlock its voltage with/without modded BIOS
I'd say both will trade blows (if you consider its value) unless you are gaming above 1440p

If you get like a $500+ 7970 lightning or toxic obviously it'll destroy the 670
that comparision is almost like saying the Titan will destroy a 7970 GHz

7870 Tahiti LE or a 7950 Boost on the other hand? Crazy bang for buck given you don't CFX it (re: all the frametime reviews)

I don't know why you'd be comparing a 7970 with a 670 when ...7970 beats a 670 every time

The 670PE came in today and I must say it's pretty awesome. I am able to run every game I have on max settings at what is seemingly over 60FPS. BF3, FC3 (w/o AA) and PS2 are running fantastic. Still not sure if I want to return it and get a GHZ 7970 though. I guess I'll give it another day or so.

Also, I ordered a 250GB SSD! When that comes in I can finally format everything and start fresh.

No point to return it. Simply enjoy it as its an amazing card
