7970 CF or 680 SLI?

OP: Read over people's experience, opinions and comments and make the decision yourself.

Both have issues and history, but both will give you a damn good setup.

Agreed. Some people pretend to be neutral here but they aren't. I disregard the pretenders opinions more than I do the people who openly admit preferring one brand. I'm about as neutral as you can get though. Proof being, I've been called an AMD and nVidia fanboy! :D

What normally happens here though is that anything people can find to beat the brand they don't like, gets used in wide rambling incoherent arguments. It's probably similar elsewhere but to be honest this is the only forum I frequent.

As some people know, I've used both 7900 series CF and 680 SLI and honestly, when you look abstract from all the nonsense, they're both as good/bad as each other. The flaws/benefits don't balance each other out perfectly but you end up with - like you say - "a damn good setup". :)

Bad crack greg, your accusation of being dishonest and putting out misinformation has came as a shock not to mention quite offensive.

My accusation holds true. You stated that the memory bus of the 6 series is a limiting factor but show me where? If correcting you is quite offensive, I have no words!

In the one sense user reviews are to be trusted but then when it suits, your posting tech reviews from when not to mention stock v's auto boost?

I'm well aware Nvidia have some driver improvements, but AMD performance increases haven't stopped since the 12.11's they keep bringing more each time.

Oh noooooo, we are back to the auto boost argument we had when the 680's were first released :( Again I praised the 12.11 drivers because they bought the 7 series up to speed but sadly you and others discarded any driver improvements that Nvidia brought. You can't say we want to test our fastest drivers against Nvidia worst? Those charts hold fair to my own findings with 680's and Titans and yet you have not shown anything that proves different. I am afraid I can't go on your say so only. I need to see proof and you bring none.

This vram debate is mental tbh, shot down in flames for daring to have an opinion and suggest that the 6's can't cope in the same manner that you were shot down in flames last gen for having an opinion saying the 570's couldn't either-and we know what happened there.

It has always been you who has been staunch that 2GB isn't enough and then Spoffle decided to join in of recent times. I have happily played with SLI 680's at 5760x1080 and had no issues with VRAM or the memory bus size. Frames were playable with very high settings. It was only when I went to max settings, I couldn't cope because of either (A) unplayable frame rates or (B) not enough VRAM but they were both linked in all my experiences. You again are harping on about something you know nothing of.

User experience proves my point because I have user experience. You don't so why keep on about something you don't know?

This place is a joke at times tbh, one minute it's how dare AMD charge the same as Nvidia's 3Gb, then it's shouts of 'out the box performance' and people don't oc a la stock 680 vs stock 7970- to then turn around full circle when the Titan is priced where it is, now my interpretation from some here is that 2Gb is enough but 3Gb isn't and only 6Gb will do?

I have let things go about misinformation regarding how the rubbish 256Bit bus, which it is for 5760x1080 gamers...Performance would be much higher if it was a 384Bit bus and in turn beat the 7970's more. I felt enough was enough when postings of 35% faster than 680's at high resolutions jumped to 40% and then 45%...Enough with this tripe please.

I missed the rest because I feel the points I have made in this reply and the post I made earlier with the graph shows quite clearly that VRAM/256bit bus isn't an issue.

Edit:

The OP now has something to see and read on what he could expect to get frame wise from 2x680's/7970's/7950's or even a Titan or 2. This is valuble info and all this crap about the 2GB of VRAM isn't enough or the 256Bit memory bus is rubbish isn't holding true in those graphs. Hopefully the OP has enough info and we can put this debate to bed.

Indeed. The headline figure of 35% from my review often gets extrapolated across all games or it becomes an average. 35% was BF3 and while both were overclocked. BF3 was the buzzgame at the time hence that forming the headline. It's important not to misinterpret results.

(A) always happens if (B) happens in my experience as well. Assuming that's the case still now because Tommy said my findings weren't very useful anymore as they're on old games but then uses my review % figure so can't be that useless! ;) :D

At least one thing has came out of this is that there is acknowledgement at long long last that I'm not making a song and dance about the vram difference between 2Gb/4Gb 670/80's and it's all about 67/80's limited performance package v the higher spec performing capabilities of the 79's.

I don't need to prove anything when you called it yourself, it's embarrassing now, I rest my case for the jury to decide...

Yourself and rusty are in the dock with me, so no need for you both to start all over again, that's my opinion and I'm sticking to it, if anyone doesn't like it tough.:D

:D :D :D

Of course it is rubbish. It would be winning far more games if it had been a 384bit bus. The trouble with your quoite Tommy...It is winning 7 out of 14 games with a rubbish 256Bit bus :rolleyes:

See my point?

As always, please ignore and stick to the RTM please

Talking about 2GB not being enough implicitly assumes that 4GB will do better unless you state/acknowledge otherwise. Which you didn't for about 15 posts.

Did you not look at the performance graphs? It's not an opinion lol. An opinion would be stating that you don't feel a 256 bit bus card is worth getting because..... I agree that the 7900 series is a better option - especially going forward - but this point has only found its way forward recently. Previously, you've been making, for months, absolutist statements with regards to the limitations of the 256 bit bus and then just incorrect statements regarding the VRAM. That isn't an opinion.
 
What that review does not make clear is when each bench was made, They could have been using Old AMD drivers for all i know, so i will ignore them all ;)

How very short sighted of you. As all review sites re-benched post 12.11 I would assume that as a minimum it was these drivers.
 
The 256bit bus isn't as limiting as you and Tommy are making out. The general gaming PC populace game on 1080P monitors and the 256Bit bus is plenty for this resolution. It is when you start to go triple screen it starts to slow up but the 670/80's can also be memory overclocked, and this in turn helps that bus and allows for more fps. I agree it was a bad move for triple screen gamers but again, they are a minority market.

Honestly, I don't think you read what people actually say, you seem to read what you want them to be saying.

Most of what I've been saying is that the VRAM quantity coupled with the 256bit bus is not going to be good enough for future games. As I've brought up multiple times now, how do you think a Kepler GPU is going to cope with studio quality textures, at high res with AA and other VRAM consuming effects added on? I don't think it's going to be not very well.



If you are referring to me, when did I say I know nothing about it? The only thing I have said I know nothing about is PhysX. This doesn't mean I can't say I like the effects and would prefer to have them in a game because I don't know the coding of it on a hardware/software level.

There's been a number of topics that you try to wade in to, stating that you don't understand the technical aspects of it, but then attempt to argue the technical aspects. The reasons being that you very often can't see anything but criticisms of nVidia, whilst ignoring the topic and reasons for it.

As for PhysX, again, you're acting like I've said you're not allowed to, or shouldn't like the effects that PhysX brings, my argument is always that the effects PhysX brings DO NOT need a GPU to run them, and that nVidia purposefully gimp PhysX's CPU performance to make PhysX on the GPU look better, and that the way nVidia are using and abusing PhysX is bad for everyone. But don't let that get in the way of you only being able to see nVidia being criticised and getting unhappy about it.


Maybe you should swat up a bit because you are a triple screen gamer and Crysis 3 uses more VRAM than your 7950's have available. I linked a GPU-Z image showing how Crysis 3 used 3.8GB of VRAM at 5760x1080. The advice given to the OP from yourself and Tommy is "7950's in CF". That is fine and good advice but now you are stating how the 2GB 256bit bus can be a limiting factor... You are contradicting yourself. Future games will only get worse, which from your advice will render the 7### series useless except for the 6GB 7970.

I think contradicting doesn't mean what you think it means.

I'm saying that 2GB on 256bit is going to be a limiting factor far quicker than 3GB on 384 bit will be.

I refer you back to the bit where I said I think you read what you want people to be saying, not what they are saying.



I know Tommy and Spoffle will defend AMD to the hilt but do it with honesty and stop giving misinformation... Where is the 256Bit bus losing out? Where is the 2GB VRAM losing out?

It's quite amusing that you say this, because you don't seem to be able to handle any criticisms of nVidia very well.

When someone crits nVidia you start crying about "hate" whilst completely blanking the actual topic.

You need to be able to see the difference between defending nVidia, and rejecting rubbish that people speak.

People love to talk smack about AMD, and incidentally, most of the time it's people who have no idea what they are talking about, or who don't understand the difference between personal experience and an issue that affects everyone.

People talk smack about nVidia because frankly nVidia do a lot of things that attracts smack talk. I dislike nVidia because of the stuff nVidia does, and my dislike of nVidia has nothing to do with AMD, and I have the luxury of not having to buy nVidia hardware because they very rarely offer more value for money, so I only buy AMD because of nVidia, not because I like AMD.
 
Again you bring nothing to the table to back up anything you say Spoffle. You are quoting me on things and just going off on a tangent.

Show me where the 2GB on a 256Bit bus is a limiting factor? You have provided no proof or even given any evidence to substantiate your claims.

Bring proof or pipe down.

I have provided enough evidence to show how the 256Bit bus on 2GB is more than enough at triple screen resolutions.
