When amd has to drop the price and overclock the 7970, you know they needed something to make it competitive. When people are pouring into the marketplace and on ebay you see "selling 7970, upgraded to 680" or "trade 7970 for 680" you know the 680 is better. Now, its not perfect and the 7970 is better for larger resolutions and I strongly feel its scaling is a lot better in two or more cards. Overclocked, a 680 will blow the 7970 1ghz. Its an upgrade, something better. Is it leaps and bounds better? No, but its better, thus an upgrade. its like switching from ls6 to a z06, not a huge increase but noticeable.
As far as the 590, its definitely better than one 7970 or one 680, but its hotter, you have to contend with sli (when its an issue), consumes more power, and you're only upgrade path is another 590. 1.5gb of vram becomes a factor with higher resolutions. The 6990 is a better card in terms of performance but you have to contend with crossfire and the heat and noise. When one 6990 is noisier than two 590s, you wanna think twice about running a stock 6990.
I'm not a fan boy of either side. I recognize a cards strengths and weakness and I make logical recommendations based on what the user needs. As I mentioned to Testier early, its a great card but if he's looking for the next step (and I stress step not level wink.gif) the 680 would be it.
Personally, i would keep it and add another 7970 down the road.

i can't fully agree with statement cause as of late the 7970 is the best bang per buck as far as Highend single gpu goes the gigahertz edition trade blow with the 680 majority of the time winning most games so to say the 680 is an upgrade is totally not valid, a side-grade sounds better, you also mention that he 680 overlcock can beat a 7970 1ghz thats true, but is also true that nicely overclock 7970 can counter that with ease i'm not right?. 680's are fantastic cards but at this point in the game they less attractive with that price point.... this is just my 2cents on the matter thumb.gif

Anything past this even 1290MHz will artifact. The memory was cranked to 1650MHz and I have not yet found my memory maximum. Voltage was set to 1.299 biggrin.gif and fan speed cranked to 75% to control the heat. Temperature hovered around the high 60s to low 70s during 3DMark 11 and Heaven. Keep in mind that at 75% speed it is annoyingly loud and I won't be running this 24/7 or even during games as I don't really need the extra performance.

Spec for spec, I've got to have one of the highest 3DMark 11 and Heaven benchmark scores among 7950 owners Warning: Spoiler! (Click to show)


Just wanted to drop in and show off the performance of this Godzilla of a card thumb.gif

That's actually REALLY impressive. Wow! For reference, here's what my rig does at 5050MHz CPU, DDR3-2200, and my 7970 at 1300 / 1800: Warning: Spoiler! (Click to show)

Yes, I am impressed myself and was blown away. I couldn't break 10K with the two 7970 lemons that I owned before settling for the 7950. One couldn't move past 1150MHz on the core regardless of voltage and the other was voltage locked. Comparing our scores, your i5-2500K is faster, our ram is about equal in speed, and your 7970 has an additional 15MHz on the core and 150MHz on the memory. Did I mention I only spent $310? LOL I kid biggrin.gif

Did I mention I've had this card since the 2nd or 3rd week of January? tongue.gif

These make me sad... But then I paid $340 for my non-reference 7970 on an open box deal, so that's not terrible. But definitely outperformed by a $310 card frown.gif I haven't pushed my overclock limits yet, but I know high temperatures will be my ceiling, as I use the card on a 1440p monitor.

What are your max overclocks on your older HD7970s and are they really slower than this 7950?

Wow that 7950 is really impressive. I am wondering what a 7970 can get at same clocks? 1285/1650.
HD7970 at 1300/1800 is only 3.9% faster than 7950 1285/1650.
But too bad not all of them will clock that high.

Will you run Heaven and 3DMark at same clocks? 1285/1650 for reference sake
