Can two Sapphire 7970 OC edition max all games on a 2560x1600 single monitor?

Phusius · May 18, 2012

Assuming you OC to say 1150/1650 which is pretty easy to do on that card

lot of reviews show 7970 CF blow 680 SLI away and a single 690 away.

This is probably something you don't need to ask considering it's been reviewed at the resolution you are stating. http://www.techpowerup.com/reviews/ASUS/HD_7970_CrossFire/

HD 7970 in Crossfire is ahead by 23% over the GTX 590.
HD 7970 in Crossfire is ahead by 35% over one HD 7970.

GTX 680 in SLI and GTX 690 are ahead by 25% over the GTX 590.
GTX 680 in SLI and GTX 690 are ahead by 42% over one HD 7970.

A factory-overclocked HD 7970 is behind by 6% over the GTX 590.
A factory-overclocked HD 7970 is ahead by 8% over a stock HD 7970.

Assuming ideal parameters and scaling is constant (bet. stock and overclocked Crossfire setups), we can extrapolate that:
Factory-overclocked HD 7970 in Crossfire is ahead by 25% over the GTX 590.
Factory-overclocked HD 7970 in Crossfire is ahead by 38% over one HD 7970.

And the "Wait, what?" reaction is more of the fact that you already have a GTX 680, and it would be easier for you to get another one instead of two HD 7970s. There's a reason why there are a lot of HD 7970s and not a lot of GTX 680s, and it's not because of "production difficulties."

yes you can max every game ever made with no problems with just 1 HD7970.. ive played ALL of the so called system killers.. none defeated mine on a single monitor... so all you need is 1 HD7970 and you can max ALL games if you use single monitor...

ill challenge any game requests though that say the HD7970 can NOT max a certain game with a single monitor. im looking for the very best graphically complex games. highest polygon counts per character/object is a must.

Hard Reset? Dragon Age II? Metro 2033? Total War: Shogun 2? Battlefield 3? Crysis 2? Batman: Arkham City? Just Cause 2? Skyrim? The Witcher 2? All at least 60fps?

In a lot of games the 7970 scales much better than that. The performance summary is kinda destroyed by the likes of BF3 and Skyrim. Generally it does very well and it will max out games at that resolution.

maxing for me means an average of 60 FPS and a min of 45. Crossfire 7970s cannot maintain that in metro 2033 - they have an average of 39 fps, which means the game drops to unplayable levels in certain scenes. Thus you just lost your challenge.

For some it means 30+ FPS.

But Metro is heavy, I'm not sure anything can max that if you want 60 FPS.

You know Frick, you should seriously considering changing that F into a P. You're approaching d.d.d. levels already.

the54thvoid · May 18, 2012

7970 crossfire is very powerful.

BUT, crossfire doesn't always work and that's the massive problem. SLI tends to work better but you'll probably get micro stutter either set up

But like folk have said, you have one 680, get another, that will perform very much the same.

You were wrong. I mean if you would've been right I would have agreed with you, but you're not. I assume you took those numbers from the performance summary pages? BF3 and Skyrim shows zero gains from crossfire, while other games scale quite well. So it is flawed. It depends a lot on the games you play.

EDIT: And frankly I'm offended at the notion I'm like DDD. I'm WAAYY more irrational than he can ever hope to be.

its right tell him go with another gtx 680, but bring out with this numbers without show a real bench with 7970 oc in crossfire vs gtx 680 sli its not good , if we have to write without prove well i can tell you i have 300000000 billions € inside my bed xd , dont make nvidia fanboysm him just ask a simple question xd

20mmrain · May 18, 2012

I wouldn't take it so personally. People are just stating facts (For the most part)

In short bud.... Yes 2 HD 7970's OC'd to those speeds would max out all games at that resolution. (Not including AA in some though Example Metro 2033). But you would get the same results from a second GTX 680 (and actually a little worse when it came to higher resolutions and AA)

Both are great cards and either way you go the performance is so close you won't be able to tell the difference. If you are asking because you want to buy the HD 7970..... I would sayu go where your pocket book can take you.... and enjoy

LifeOnMars · May 18, 2012

Why not go for a third card at that resolution? That's where the scaling hits with tri sli or crossfirex, not worth it at lower resolutions. Yes you may have driver difficulties for some games with a third card but generally it's going to be with the less demanding games which only need the one or two any way so just disable for those.

i may not beable to maintai na solid 60 on metro but i can get to 60 no problem on a single monitor.... no game atm can bring down my system with a silly single monitor configuration it is laughable at best.

throw a hybrid physx card in their and see how metro runs , maxd 5870's xfired and at1000 core do well 40-50 fps max IQ ,with a physx boost so the same would apply to 7970's, i got a cheap gt240 for that(52 quids), but batman AC is pushing me towards a 560 soon,

and thats ultra settings + morpho AA + physx high
