    Basically the title... what are you guys expecting to happen.. atm they're sitting around 700 679 at most vendors in aus... I'm scared to wait a few more days to see the 290x being all amazing and them pushing the 7990 prices up ><

    which would suck...

    thoughts?

    If reports are true, the most you will be able to expect out of a 290x is 1.4x a 7970. That being the case, the 7990 should retain its pricing pretty well, least for time being

    That said, will it go up - not sure. I suspect the new cards will be in the 700-800 price range

    that just worries me... how did the 6990 prices fair last gen

    Hmm... so will crossfire work with a 7990 and a 280x? even without the physical bridge.

    I would say that it won't go up in price. The 7990 is a flawed card and there is a reason why its EOL after such a short amount of time on the market.

    Besides some of them having coil whine, it's a perfect option for 7970 xfire in one card. If it wasn't for the coil whine, they would be really quiet as well, the cooling solution on them works perfectly. They are also built pretty damn solid and the backplate is a nice aesthetic addition, i was actually surprised the support it gave the card as well, as there was minimal flex. Compared to other cards that have lighter coolers, i was surprised the 7990 didn't flex as much as they did (it was almost straight when in a pcie slot)

    the 280x and 7990 should be crossfire compatible considering that the 280x is a basically a 7970 ghz edition - you will need to use the crossfire bridge though.

    The 290 and 290x do not have the crossfire fingers as they supposedly have specific hardware for crossfire that allows running it over the pci-e bus as per 3rd slide here:
    http://www.pcauthority.com.au/News/360180,amd-r9-290x-8211-inbound-and-specs-confirmed.aspx

    I doubt they actually have hardware and rather speculate that they would do it in software. Which would be how they intend to fix crossfire/frame pacing moving forward.

    If you run by the numbers:
    4.3 TFLops/2048 shaders for Tahiti XT
    5.6 TFops/2816 Shaders for Hawaii

    Approx 2.1 Tflops per 1k shaders for Tahiti
    Approx 1.98 for Hawaii

    You'd expect that Hawaii would be clock for clock 10% slower, but with more shaders it comes out on top.

    Comparing apples to apples

    you get 4096 shaders on a 7990 card, (or 8.6 Tflops) vs 5.6 Tflops for a Hawaii - therefore you expect (approx) 50% more performance out of a 7990 than a 290x before overclocking comes into it. Add another 7970 to a 7990 and you're at 12.9, vs 11.2 for 2x hawaii.

    Gut feel:
    7990 won't change price as they want to clear it
    290x will debut at $750ish street price, but will quickly (2-3 months) drop to about $500.

    I have yet to use one, I would definitely water cool it without question.. unless they all have coil whine, it shouldn't really be a problem. cause your local store will always give you a new card if thats the case.. least in my experience, anything with coil whine has been swapped. if you buy from an online retailer it might be more hassle though..

    anyway, I had a look at some reviews with it in crossfire with a 7970 and they're phenomenal.. it ruins 2 titans in sli lol

    Ah okay, I hadn't seen that the 280x still had the teeth. I've never noticed the microstutter everyones talked about with crossfire... maybe I'm just unaware and it is happening...

    Hi, i dont run water cooling, sorry. too much risk and outlay for my liking-no offence.

    The temps are awesome.
    They really surprised me.
    mid benchmarking 3dmark the 7970 sits in the 70's and the 7990 is allways 10+ degrees cooler at minimum - it cools bloody well!

    I am running a AX 1200. about to swap it with my daughters AX1200I as i got some white cables for it lol.

    lol all my systems(4) run ax series psus. 2x ax1200(black sleeved cables) 1x ax1200i(white sleeved cables) and 1x ax850(white sleeved cables)

    i'll take a photo :)

    Cheers, Alan.

    Haha sweet man, no offence taken :p I think water is the only way to cool anything in the system now.. nice and quiet. I'm running the 1000w seasonic platinum.. rekon that'll take the 7990 + 7970 across the line? is that a reference 7970 with the blower design? cause that would explain it :)

    I run a single 7990 under water, thankfully I don't get coil whine. It does heat up the water enough to warrant me dropping my cpu overclock by 100 mhz. I don't have the best watercooling setup out there though. Temps on the card are 47C under full load.

    PS. I run a 750w PSU and think I could run another 7970 without too much grief.

    Nothing wrong with that loop mate :thumbup: Yea I'd assume all the temps would be coming from your cpu under load at that clock.. my 3770k is around 65 and my 2 7970's in crossfire are at 45 degrees, which would just be a little higher than water temp. How hot does your 4770k run? Oh and nice work on finding one on the forums.. been putting up WTB atm haha :p

    Coil whine would absolutely do my head in. Couldn't imagine anything worse than hearing a high pitched noise when putting the GPU under load. Personally, I haven't heard how bad it actually is on the 7990 but it certainly is an issue for some who have purchased this card.

    You can't turn off crossfire so the card is effectively useless in older games and games that are not supported.

    Frame pacing is only fixed on small bunch of select titles.

    Also what is to say that AMD will continue to support this card in the future? The driver issues that plague crossfire (especially the frame pacing issue) have make me extremely skeptical about whether this card is suitable for anyone who plans to keep the card for at least two years.

    I'd love for you to prove me otherwise, as I'd buy a 7990 right now if the above issues weren't there.

    well mate, coil whine wise.. thats usually a problem for all electronic components and that comes down to that particular unit. easily rma'd. support for crossfire in a few years? well they just re released their 7970's as 280x's... and they still will be used in crossfire, so I'm sure you'll see ongoing support for those as well as their solutions for the 290x. Crossfire in older games? does that really concern you? rift is probably the only game I play based on an older engine (dx 9) and what not and it runs beautifully on my 7970's cf with the latest drivers. what older games would you be concerned about? and which ones would require more then the single 7970 performance the 7990 would offer in that scenario?

    Thanks! From memory the seller had another card he wanted to sell, might be worth PMing him.

    My 4770k does 4.3 comfortably at 1.2v (I've tinkered a bit with this, and it is stable just below this - but I need rock solid stability) Load temps are low-mid 70s when the GPU is running full out. I can get up to 4.6Ghz at about 1.35ish v but temps are in the mid 80s when the system is under serious load, and I'm not comfortable with that.

    For the record I haven't had any problems with crossfire on the 7990 in any games. I do run single monitor though.

    You've been able to turn off crossfire on the 4870 x2 and 6990, I would assume you can do it on the 7990 as well, its changed in the catalyst control panel.

    Also the 7990 will be supported for as long as the 7000 series is supported, or the 7970 is supported.

    Considering the 6000 series is still supported and isn't going away any time soon I don't think its something to worry about.


    The issues with the 7990 are simply frame pacing and crossfire support, something you will encounter when crossfiring the 290x etc.

    In my opinion the 7990 is the deal of the decade
