7990 vs SLI 770s For 3x1080p Surround?

Leamon · Aug 10, 2013

Hi,
If you haven't heard, the previously $1k 7990 has dropped to only $600! It still includes 8 games, and now with the frame-tearing issues all but fixed, I was wondering if I should get that card instead of dual 770s.
According this this article: http://www.guru3d.com/articles_pages/geforce_gtx_770_sli_review,22.html I will get better performance with a 7990 than I would with dual 770s.
It seems to me that the 7990 is a much better deal.
What do you think? What advantages do the 770s have?

7990 would be better. Although if those are 4gig 770's that would also be a viable option. Having 2 gig 770's though, would be a limitation.

The 7990 also has a slightly higher memory bandwidth which helps with higher resolutions.

Edit: If you like physx or 3d vision definitely go nvidia!

You should read this Tom's article: http://www.tomshardware.com/forum/id-1761907/radeon-7990-price-cut-699-catalyst-release.html#11326701

Consider the 7990, especially bc of the latest patch and price cut. The game bundle is a nice extra. But you know all this. If you need one more opinion to tip the scale, go for the 7990. Place a waterblock on it later, and you'll have a competitive card for a while.

Thank you, you've all been helpful! I love how the 7990 can preform equal to SLI 780s in many games

Hmm, you might be a little biased. Tell me, was that extra $700 worth 4 more FPS?

theclouds · Aug 10, 2013

And you can boast you have AMDs flagship card! Another perk I didn't mention. I'm running away before the pitchforks arrive...Not trying to incite a fan war.

Leamon :

Single gpu wise the 780 is 15% faster. That is more than 4 frames.
I highly doubt that the 7990 beats the 780sli setup. The 780 is only 5% slower than a titan.

Fine, you don't believe me? Check out the benchies on this page: http://www.guru3d.com/articles_pages/geforce_gtx_770_sli_review,22.html

Leamon :

The agony.
That is 770 sli, not 780 :pfff:

780 sli is beats the 7990 in every game.

You are so wrong.

Get a clue before accusing me of bias, please :no:

. I had two 1200/1800 MHz 7970s for a little over a year before upgrading to these 780s, so I think I know something about how the two perform relative to each other (at least at 1440p).

And yes, the extra 20fps & ability to enable 2xSMAA in Crysis 3 over two 7970s was worth it to me.

Even if you take 10% off the Titan SLI scores here to simulate stock 780 performance, the 7990 (= 2x7970) is almost always decisively beaten at 1440p...

The only times it is not are Crysis 1, F1 2012, Sleeping Dogs, and Skyrim. And the only one of those that isn't CPU bound is Sleeping Dogs.

Look at the benches i posted...
I can post more too.

@OP I'm not saying the 7990 is a bad card. You are just terribly misinformed.

You've got to be kidding me! First of all, although the article has 770 SLI in the title, the article includes benchmarks for SLI 780s as well.
And oh yeah, IT'S $700 CHEAPER!!

Are you playing at 5760x1080?

You edited your post....
You said it was a 4fps difference, and it's not. That's the main thing i'm gripping about.

Yes I am.

Hitman absolution runs bad on nvidia cards.

Leamon · Aug 10, 2013

BigMack70 :

How's this for a point? $700. Anyway, I'm playing at a higher resolution. 3x1080p

Djentleman · Aug 10, 2013

BigMack70 :

Exactly what i've been trying to get across.

Like i said though, you can't go wrong with the 7990. Especially at 3x1080 resolution.

Leamon · Aug 10, 2013

BigMack70 :

Thank you for clearing things up. I have to say though, by the time I can afford a 7990, they surely will have fixed any driver issues involving eyefinity. I am 16 and don't have a job

. Just one more question: do the driver updates eliminate the screen tearing associated with AMD cards on eyefinity, or only the micro stuttering?

BigMack70 :

I just wanted to reinforce this point. True a fix is coming but if he is buying such a high end card he likely wants to use it asap and not wait for a fix.

Djentleman · Aug 10, 2013

Amd constantly says "we're going to fix it" but it never happens.
I'm surprised they did something about the latency problem. They've been doing that since the 4000 series? So that's been about 5 years.

Just a fyi. I have a 7850 in my girlfriends pc and i love it. No fanboyism here.
