AMD 7970 - GPU Question

[atle]

The 7990 has 2 gpu's on one card.

 

But some of the games i play does not work with crossfire x.

I tested this with myn two 7970 cards but now one died and i'm looking for a new card.

 

So i was wondering if i bought the 7990 would it only use one of the 2 gpu's of the card then?

 

If so i might buy the titan the lost performance on other games is not something where i'm really worried about.

[Hirad123]

Yeah i'm pretty sure unsupported games will only use 1 of the gpu's

Wow, that's stupid. Thank god I found that out before I bought a 7990 in the future or something/

I want to point out that "unsupported games" usually means games that won't need a second GPU to run well. 

AAA games, for the most part (~90% of them) will support it, and they are the ones that will need both GPU's. What's the point of having 1 super strong GPU if indie and old games will never utilize all of it's power because they simply don't need it to run at their best?

That's the exact same situation as having 2 GPU's and those games only using 1 of them. So honestly, choosing 1 GPU over 2 GPU's doesn't change anything except the ~10% (probably less) of AAA games that won't see both. And you will get less performance on the AAA games with only 1 GPU. But those are the only differences.

From the message it sounds like you already have 2 7970s. In which case don't bother getting a 7990, and if you want a single card set-up go for a 780 or a Titan.

It's still useless since the OP could get the 7990 performance for 350$ then.

The frame stuttering, frame times,heat output, power consumption, taking up extra ports.

One of his 7970's died.

Yes, but only for certain games. Most AAA games will use both cores, meaning they will fully utilize the 7990. It's old games, indie games, and the very small percentage of AAA games that don't support Crossfire/SLI that won't benefit from it, but the indie/old games are a given as they don't need that much GPU power to begin with. So the only concern is the AAA games that don't utilize crossfire, which is likely a miniscule number.

I would still get the 7990.

Yes, but those obviously don't matter to the OP since he had 7970's in Crossfire to begin with and would be fine with said concessions. :| Do math.

Why the hell get a 7990 when the OP already has a 7970 which could be "made into" a 7990 by adding another 7970!?!

Because those are the choices the OP offered. Get a 7990 or a Titan. :|

O wow so many responses already :o.

 

And yes one of myn 7970 cards died yesterday, he was not even overklocked.

First myn desktop turned off middle of some call of duty.

And when i tried to start up agian the card smoking.

 

That card is only 1/2 of a year old.

So i will get another one or i will get myn money back and chose another product.

But 95% of the time i play the same game where crossfire x is not working.

So buying another 7970 would be a waste in the first place.

 

Thats why i looking to buy a single higher end card.

I only don't know of that is going to be now or after myn other 7970 is not doing the job anymore.

It really depends on what options i will get whith myn garantie of the death card.

 

I'm playing on triple monitors btw so thats also one of the reasons why i went with amd in the first place.

but knowing that we now have the gtx 7990 multi gpu and the titan as a single gpu and both 6k memory.

So thats why i looking at those 2 cards. but mutch will depend on what i can get with myn warranty on the card.

[A10-FTW]

questions...   ^_^

 

what monitor you have ? (900p, 1080p, 1440p, 2160p yey)

 

and, how did that die ? (that 7970 is a awesome card)

 

what PSU you have ? (and cpu to by the way)

If the card is just 1/2 year old and you didn't overclock it, you should definitely try and get a new one in for warranty.

Just RMA the card.

95%? What game u play? Something is not right with your system brah.

[atle]

Yes only half a year old.

And the funny thing is when i bought that computer i heared a strange sound when i running using crossfire x games.

So i went back to the shop and they tested myn cards over there.

But they said there was nothing wrong whith that.

Guess i was right after all.

 

Most of the time runescape. I have a huge clan over there thats the main reason why i don't have time for other games.

Only happens a few times when we all play other games together.

 

I have 3 monitors 1920 * 1080p

I guess the problem with the card was there already from the start but that card was in sleep mode for so long knowing i only played 9h call of duty.

And a few hours assassin's creed he probably died in the first week i played more cod.

power suply: zm850-hp plus.850w

cpu: i7-3770s

[A10-FTW]

in the good news, looks like you have a good system (good cpu, good PSU, and a 3x1080p)

 

like xAcid9 say, just RMA the card

 

 

 

Titan is a great option, but you will not have the same power that the Malta 7990

 

the good news is, you already know the power of 2x7970 (that is essentially a 7990)

 

so you will know if it is ok losing some power for a 3x1080p

[ExDreamer]

Had to ask,why don't you buy another 7970?
