Asus DirectCUII HD7970 or GTX670 - Page 3

Your best bet is a 7970, if you are wanting to save money get a gigabyte windforce 7950 over clock it and you'll be faster then the 670 for less money

From what I've been seeing is that the Gigabyte actually has some trouble hitting high OC potential. The sapphire 7950's look pretty good though. I've seen people scoring much higher clocks on those cards.

Overclock ability is random. Brands have nothing to do with it and it's down to the individual silicon.

I don't think it is "much" faster, simply faster.

That's not entirely true. There are still some games that perform better with nVidia cards (such as WoW). Also, I've been using my GTX 670 at 70% power limit lately (not stressing it enough, as I don't have time to play stressful games for a while), and it's keeping up good FPS while being inaudible, and my whole system only draws 170-175 Watts from the wall in games while still boosting over 1200MHz time to time! I tried that with the 7970 too, and it was going up to 233 Watts at 1.034V --as set by MSI Afterburner--980/1500MHz (tried a low-power profile with decent clocks), but the GTX 670 got better fps in games that favor it. (Overall, the 7970 wins, of course, but it's good to keep in mind which games / applications one wants to use their card for mostly). A GTX 670 is great for small cases, where 7970 might not get full overclocked utilization due to excess heat, unless water-cooled.

Did you manage to use the Sapphire 7970 with a fan speed under 50% under full load?
post #26 of 42
id go with another 7970 a cheaper one maybe with the 12.11 drivers a 7970 even beats a 680 only thing 680 has going for it now is physx which only a handful of games even use.

Yes - it all depends on the core clocks you use and max voltage. It does go over 50% on the 1100/1575MHz setting though to stay within good temperature limits (70C / 80C).

Mmm the Sapphire or the Asus... Anybody has any experience with the non-TOP Asus? What the max. overclock is for example? And how loud it is?
post #29 of 42
They both have good reviews noise-wise. Sapphire has a better chance of not being voltage-locked though, so if that matters, go with Sapphire. Just look at the models you like and search for reviews. This is a good place to start:

http://www.techpowerup.com/reviewdb/Graphics-Cards/ATI/HD-7970/

But keep an eye on what driver versions are used for their benchmarks. Catalyst 12.11 is going to be more accurate to what you'd expect from your future card (vs. old reviews with something like 12.4).

Do you have any idea how far you would be able to OC a 7970 without voltage tweaking (generally speaking I know it depends on the chip)?
