Hello all!
I am thinking about selling my GTX 670 and upgrading to dual-SLI. However, I am not sure whether I should SLI GTX 770's, Radeon 7970 Ghz's, or wait until the next-gen 7970 GHZ comes out and SLI that.
Thank you all in advance! :)

You dont sli AMD GPU'S you Crossfire them, The 770 sli will outpreform the 7970ghz due to the fact crossfire is currently broken. Look at the toms 770 review on the front page and see for yourself what i mean in the dual gpu results.

Well. the next gen AMD won't be out for months.... (probably Q4 2013 so 4+ months)

and the 8 series is just going to be a die shrink of the 7 series. (down to 28nm) so you can expect 5-20% performance boost.



I would personally wait for the 8 series (it'll be a while) and see what it has to offer. but right now, best performance for your money is pretty much a GTX 770 or a 7970 with a good cooler and overclock it.

7970 overclocks better (if that's of interest to you) and comes with free games. It's an overall great deal. However, 770 is still a little faster, and while it comes with no games, if you're thinking about dual cards, I'd suggest SLI over Crossfire at this moment. 8970 is speculation and no suggestions can be made on that card because we don't have official specs. No one can say whether it'd be worth the wait or not.

amd 7k series already made on 28nm node. if 8k series will be on next die shrink it will be TSMC next 20nm node. most expect amd will launch something at the end of this year but personally i think 20nm gpu won't coming out until next year. amd could do paper launch just like they did with 7970 though just to 'officially' launch the card this year with true availability only comes next year

so far it is still pure speculation. nothing is confirm yet. AMD can deny such rumor anytime just like they did when almost everyone believe amd have something that perform much better that 7970GHz and will launch it in late Q1/ early Q2 this year

You're clueless, how can you say stuff like this when the 7970 already uses 28nm....smh. You have no idea why you're talking about. The 8000 series is most likely OEM and the 9000 series is what will possibly come out in q4 with a smaller 20nm technology.

Ya ya. I've been drinking a bit tonight and reading websites wrong lol.

And I really don't think they would move onto 20nm tech (especially since Nvidia didn't move onto 20nm yet) and the yields are going to be terrible if they do...

AMD's been cutting staff left and right (15% of their engineering team last year)... They're pretty much doing whatever they can to get back in the black on their balance sheets....

I'm actually worried if they'll put out a decent chip (both CPU and GPU) for the next gen... especially with Intel stumbling pretty bad with the hanswell desktop CPUs... not too much of a performance improvement....

I understand, sorry for being a jerk about it, didn't mean to come off that way. Honestly, I would be very happy if and brought out the 20nm chips by the end of 2013/beginning of 2014. It's possible for them to do. But there is some trouble with tsmc being able to produce them for amd specifically considering everybody wants them. The rumored specs were 2x 7970, these specs are quite impressive but on paper you can't take them to directly correlate to performance. Nvidia or amd fan, everyone should want bth companies to do well in order to keep competition and realistic pricing alive.

to me this year is quite boring for gpu. hopefully we can see much fierce competition when nvidia and AMD starts rolling out their gpu with TSMC 20nm node process. to be honest i'm quite shocked AMD did not come with something that will compete with nvidia GK110. nvidia officially announcing the spec of GK110 in May 2012 (except it's clock) and amd did nothing at all to come up with something that will challenge GK110 in 2013. well maybe they putting all their R&D to their console contract and hoping that most game will favor their architecture later in the future lol (for cross platform games)

AMD 8k is same as AMD 7K, just clocks change, they skip 8k because of PS4 and XboxOne, It's a matter of taste if you are Nvidia Fan take 770 and if you prefere AMD take 7970Ghz; it's nearly the same, 7970 will consume more power but graphically you won't see any difference I think just a few frames per second, Also 770 ahs PhysX for compatible games which boosts quality and 7970 has TressFX so whatever you can read on the internet is just marketing and shit,

personally i'd go for the 7970 because it's a bit cheaper and I prefere AMD to Nvidia
