200Mhz extra core speed on the 7970 GE only adds 23w to the power consumption, but 240Mhz extra on the GTX 680 adds 63w to the power consumption, very poor scaling!
It's also a good review as it's 7970 at 1250 vs GTX 680 at 1245, near enough clock-for-clock....

7970 is underclocked at stock clock severely imo.

out of curiosity does anyone buy these monster cards to run low amounts of AA?

i dont run high AA because i have a 1600p monitor. doesnt make any difference when i turn it on. depending on how rough of a time my card is having playing the game, i will put is somewhere between off and 8.

however, i dont see myself buying this card because it needs 4gb of vram like you said.

Same results as always, with no or little AA enabled the GTX 680 is faster or as fast a 7970, turn the AA up or on though the 7970 pulls ahead, out of curiosity does anyone buy these monster cards to run low amounts of AA?

if we will see 7970GE over 1.4GHz with stock cooling, and 2GHz with ln2 ask a test clock to clock ...there is no point and even a monkey would understand

when overclocked i see ~+10% power consumption and ~+10% perfomances ... perfect scaling.

@2560x1440 high AA four games result unplayable , two draw and only one win apiece
any player who has tried knows that you do not need high AA at high resolutions because there is no difference detectable by sight

Unfortunately thats not a boost clock for kepler. Im guessing its somewhere between 1320-1350.

interestingly, the memory frequency had to be reduced by 20 MHz in order to make the card stable at that GPU clock rate. So, the resulting clock rates were 1246/1311/6988 MHz

Max boost 1324 according to that picture.

Huh? I use a Dell u3011 and a Samsung S27A850D and there is assuredly a HUGE difference with AA. 1600p doesn't relinquish the need for AA - if anything it increases it. I still get TONS of jaggies with AA turned off, and it is more noticeable than it would be with a 1080p screen because the PPI is much higher.
