GTX970OC vs 7970

Can't offer a direct comparison but my 780 running clocks that put it approx stock 980 performance was roughly comparable to a heavily overclocked 7950 cf setup - a little faster in some games a little slower in others probably a little slower overall but not significantly and was definitely smoother.
you mean just the difficulty accessing the .5 mem?
I upgraded recently 7950 to 970 and am enjoying it - although havnt done any official benches.
Also got to take into consideration the decrease in cost to run the card.
whats to consider ? if its in your price bracket and you dont game and stupid res its still better than any 290.
people may disagree there is about 1000 benchmarks showing it
so what if its got 3.5 gb mem last bit different
if its better than the rival 290 its still a good choice.whats to consider ? if its in your price bracket and you dont game and stupid res its still better than any 290.

Why pretend that prices have not changed from AMD and we now have 290X available for £250? That then makes it the direct competitor to the 970 surely?
I had 2x280x which is a 7970 in crossfire and the 970 was just as good, if anything I prefer the 970... To say it's as good as the 980x is a bit much
It still a great GPU for the price..
Even only being able to use only 3.5GB of the 4GB of vram is still 500mb more then my 780ti's have which work great at 1440p
I did the switch from 7970's to 980's and my performance pretty much doubled with around a 30-40% drop in power/heat.
Its a big upgrade and what the stock numbers don't tell you is that the 980s will hit a decent OC boost with a small volts increase. I found the 7970's to be powerful cards but they really needed 1.3v to sing.
The more you put OC into the equation, the bigger the power/heat perf. gap in the 980s favour.
For the 970's chop 10% off the speed and the same off the power/heat.

Been looking at the reviews on the 980, seems to be a monster of a card. Going to put my 7970's up on the MM along with a Mountain Mods Ascension Case and a load of water cooling gear, go take a look
Emm,at high res its less than 20% faster than a R9 290X:
http://tpucdn.com/reviews/Gigabyte/GTX_960_G1_Gaming/images/perfrel_2560.gif
That TPU graph puts it around 10% over an average of games.
Honestly,if I were you I will be waiting to see how the R9 380X/390X turns out.
Its also rumoured to be a high bandwidth HBM card too.
Bah to the graphs I say!
The 970/980 is good for a 35-40% Air OC out of the box (most seem to do 1500mhz+) and the mileage will vary on the 7970 under air cooling, maybe 20% if you are lucky and they run hot as a mofo.
I would imagine that the 380X/390X (when they are announced, its all rumour that the moment) will be powerful cards but I am not confident that AMD will get the power/heat balance correct.

After i got my 7950 crossfire up and running i did a few benchmarks and tried a few games and i seemed to get roughly the same FPS as a single 980 so it seems like a nice upgrade.
Prolly a good idea selling some of your gear together like you decided, 7970s dont sell that much by them self, 80-100 quid or so but the water coolers are still very expensive to buy new, and they dont come up for sale very often second hand so you can charge a lot more.

It's not really a 35-40% overclock though is it. Most versions out of the box are boosting between 1300-1400mhz so if you reach 1500mhz your only really going to be overclocking in the region of 10-20%. Hardocp got there 970 to 1542 boost and the average gain was only 12% in games. So huge clocks and not massive real term gains. Out of the box it was only boosting around 60mhz over the standard version on paper. It all looks great on paper but the average gains from doing so were not massive like you would think. That shows up on this forum in the game benches where the gtx970 even running at huge clocks is still mainly behind the 290x and sometimes the 290p.
