$1000 to nVidia gets me 2 GPUs and 0 games.

Man this is sad :shadedshu

My graphics cards package was drivers and a 6 pin to 8 pin Pcie -.-

Can't discuss the performance of my setup but man, they could've atleast put some software inside. (Hint to nVidia, standalone Octane license...)

Uhhh, thanks(?) guys, but please read the OP. I'm fully aware of the issues and thanks for informing me in case I hadn't, but I'm getting the AMD cards for two indisputable reasons.

The first is that $1000 to AMD gets me 2 GPUs and 6 games. Hopefully. $1000 to nVidia gets me 2 GPUs and 0 games. Just F2P credit. Which I could buy. For less than the cost of 6 games. The F2P credit not even value matching the Reloaded bundle is a pretty major misstep for those who can add and subtract like you and I can.

The second is that $1000 of AMD GPU gets me more performance than $1000 of nVidia GPU. Link posting and subjective anecdotes will probably begin now, and that's fine, but two GEs > two 680s as of the latest Anandtech review (also linked in posts above).

So yeah, until both of the above change, AMD will get the hard earned. "Stuttering" be damned.

Hi mate, thought I'd chime in. The first reason is bang to rights. Nvidia are fleecing everybody that's willing to buy their products.

Your second reason is illogical. Yes two 7970's are faster in raw power than any Nvidia combo of roughly the same pricing but that's where the problem lies. The higher fps of a crossfire 7970 set up can be less smooth and sometimes downright poor. I expect smooth gameplay at above 60fps. My 7970's ran well above that but in a few AAA titles they were not smooth at all. The were great in BF3. But in all honesty thats one of the few places i saw the benefit.
If the crossfire performance is improved for games and latency then yes, 2 7970's will be the most effective solution (when cost is factored in).
But you need to be aware that what you actually see on screen compared to what the fps is measured is very different.

AMD have the better architecture this round IMO. Graphics power and compute is exceptional. The 7970 even beats the GTX Titan in quite a few compute tasks. A single overclocked custom cooled HD7970 is the best card in the world with all factors figured in.

But as soon as you add a second, their actual performance value can be very flaky indeed. If I were you, I'd simply buy one right now. Wait till the driver fixes before buying the second. You can wave the fps and most powerful combo flag as much as you want but i downgraded from 2 x 7970's to a single Titan for the issues I have explained. No regrets...unless AMD really do a great job on their drivers. ;)

I completely agree.

The 7970 is a beast and the indisputable king of price/perf on high end graphics cards right now.

^ I'll agree to both of those, except the downright poor crossfire scaling. Crossfire scaling has some large downturns, but not that bad man.
I have yet to find a game that runs excessively poorly on two 7950's, and i mean real bad. I have quite a library of games too. The scaling isnt 100%, but its damn good for the money. Metro 2033 at over 60fps good.

I'm not a naysayer to AMD or crossfire but it is a case of 'be warned'. I had no initial problems but as i played more games on my set up it became more apparent. It really does depend on whole system configurations. I've had problems on games where other people haven't and vice versa. If you've had no problems you're quite lucky.

I also didn't mean the scaling was downright poor - i meant the experience. It's cool for some people but for a lot it is most definitely a broken powerhouse of graphics roulette. Crysis 3? Awesome, very rarely laggy. BF3? Awesome. Far Cry 3? Terrible. MOHW - didn't work in crossfire. Like i say roulette and so far you've picked right each time ;)

No loss there then ;)
But yes, crossfire has its issues, and in no way would i try and cover that up. I had issues with crossfire in farcry 3 up until the 13.3 or 4, i dont know which one i have installed at the moment, but that has sorted my issues personally. I've run those cards on 3 different motherboards and 2 processors from Intel and AMD. Skyrim had horrendous problems, then i updated drivers and it fixed them.
I think crossfire is a game of patience. I've found the newest drivers have fixed 95% of my problems, eventually they get it right. Still not having fun with Tomb Raider in Crossfire though, not for 120hz anyway.
Coming from GTX 570's in SLI, I'm quite happy with the end product.

In short, single GPU the 7970's frame time is equal or even arguably better than nVidia in some cases, just stay away from Crossfire for now.

I would say for single card to get the Ghz edition, but if you plan on crossfiring 2, the normal 7970 seem more sensible to me.
I have to say though, I got the gigabyte 7970 1100/1500, and while it runs very cool and makes little noise, it doesn't like to overclock either.
