    Guru3D did a review on this:
    http://www.guru3d.com/article/radeon-hd-7970-cpu-scaling-performance-review/9

    Some games will make a difference in lower resolution but as far as high resolutions they all seem up to par when it came down to cpu scaling.

    ahh missed that cheers.

    so bf3 isnt the best title to test your cpu oc's on :)

    nahh rich guy wait for the next nvidia beast...well i'm hoping for a reduction in 580 costs so i can stick another one in under water....(although i'd be somewhat bottlenecked and probably would need another psu).

    Its a decent step up, and when clocked, should be nigh on as fast as 2 of them :D

    yeah after a 2nd look think you are right. if it were me and i could get something for the 6970 i'd pull the trigger...

    no harm though in waiting for ones with aftermarket cooler?

    Xaser04 - I have a question for you.
    I want a multi display setup with 7970.
    3 displays of which one is a TV that will be hooked up via HDMI.
    Two others will be some 23" or 24" LCDs.

    Now my question is, do these 2 LCDs have to be equipped with DP or can I plug two DVI monitor besides the HDMI?

    I'm asking because HDMI always shares video signal with one of the DVIs, do you can't use them at the same time. I will need to connect one of he displays to the mimi-DP via the supplied converter probably, but could you shed some light on it?

    I'm not sure if I should buy LCD that have DP, the choice for some reason is pretty limited, or if I'll be okay with just the DVI ones.

    For three screens to work from the single card one of them MUST be plugged into the Mini DP. The DVI and HDMI port can be used at the same time but the third must be from the DP.

    I would recommend the following for your config:

    TV connected via HDMI
    Monitors connected by DVI (straight DVI to DVI) and mini DP to DVI (adaptor included in box).


    Mitzi76 - Please remember that I am running a very high screen resolution (3560x1920). CPU bottlenecks are much less pronounced at this resolution than they are at say 1080p.

    BF3 doesn't seem to scale with CPU speeds but other games might show a small difference. TBH though I am more likely limited by the GPU than I am the CPU.

    Thank you, this is what I though it has to look like.

    I finally buckled. :D

    Just noticed Ebuyer have got Sapphys in for only £465, which isn't a bad price, so im gona order tomorrow, wish id seen them before 11pm, as i could have still got it for tomorrow (as thats the cutoff), trouble is though, they don't show up when you select the 7900 section from the menu, only the Gigas do (and they are £480 lol), you have to click on the 1 next to deals in the red bar underneath, to get the rest up :p

    These cards have just arrived in NZ..... well I just checked the price and nearly had a seizure: $1100 NZD!!! :eek2:
    That's double what the 6970 costs and only $50 less than a 6990.

    Guess I won't be upgrading after all...

    I'd like to add my 2cent...

    I got two Powercolor 7970 crossfired.

    1920x1080, I'm averaging 100+FPS no problem, EVERYTHING maxed

    Here's the kicker. My previous setup, 5850 crossfire couldn't even do Ultra in 1920x1080 (Vid Mem was just not enough) but I can do 55 to 60 FPS, constant in Eyefinity --> 5760 x 1080, Highest possible settings.

    I've got the cards clocked at 1175 Core and 1800 Mem (7200mhz), in stock voltage.

    If you got the money, it's a HUGE upgrade (to say the least) especially coming from the 5800 Series. And these things overclock VERY well. With a bump in voltage, I've gotten this to run at 1275 Core.



    Is there any benchmark/demo tool for BF3 at the moment? Would love to make it a bit more official than just what I see on Fraps.

    sadly no. only way is to run a timedemo using fraps but even then thats useless for the end user.

    I am running Cat 11.12 which came on the driver CD.

    I havn't looked into updated drivers yet as getting everything working with Eyefnity was a bigger priority.

    regarding eyefinity, If I'll take 3 LCD's from DELL that have DP I do not need any adapter do I? 2 Monitors will be conected via DVI and one direct on DP. Dell 2312HM have DP as a standard connection.

    I have 2x5870 and will intend to upgrade to 7 series if the 2x5870 won't cut it as I want, should I expect issues regarding monitor connections??

    Note: BF3 is not my benchmark here, in my opinion MW3 was better looking as BF3 and my 5870's hammered BF3 at ultra (1920x1200) without issues.
