Upgrading 6870 to 670 or 7970

Hi, i'm going to be upgrading my 6870 after deciding not to wait for the next series 700/8000.

The two cards are basically the same price from Novatech

http://www.novatech.co.uk/products/components/nvidiageforcegraphicscards/nvidiagtx670keplerseries/gv-n670oc-2gd.html


So which one do i get? I currently run at 1680x1050 but i will be upgrading to 1920x1080 at somepoint.

I don't want to bother with xfire/sli so which card will be the best performance for the longest time.

I play games like BF3 and want to max out upcoming games like Company of Heroes 2.

  1. either card choice is fine. both over excel in 1920x1080.
  2. if your interrested in borderlands 2 go with the 670 for the physics. it makes the game way cooler.

    Yea i've been playing some BL2, although physx is nice its hardly used in many other games. Which card is more powerful, i see loads of 670 vs 7970 threads and im really unsure.
  4. With the latest drivers 7970 is certainly stronger, especially in higher resolutions with more anti-aliasing.
  5. essentially I like to put the cards in this way:

    670 Pros:
    Physx
    Adaptive Vsync for games with extreme drops in fps at split moments
    More efficient, shorter and will run cooler(as well as quieter, but silence is heavily dictated by which heatsink setup you are using.)
    CUDA enabled gpgpu acceleration in some professional programs

    7970 pros
    Resolution curve is better, can take 2560x1400 easier than counterpart
    GPGPU and OpenGL support is stronger.(Gamble if games start to run on linux more, OpenGL would be used more, but for the most part, games are run on DirectX due to near windows monopoly for gamers)
    Tends to have more vram if there ever comes to a point where a single game will surpass 2 gb(highly unlikely, but who knows)
    Handles games with crippling Anti Aliasing better(if you prefer 8x+ MSAA over FXAA)


    I tend to basically sugest between the 2 like this:

    Is there a sale on one at the moment, if yes: order the one on sale
    Are you playing 1920x1080 resolution strictly: 670
    Playing on a easy to install, and has features you can use: 670
    Are you aiming for enthusiast overclocking(by enthusiast, i mean litterally, using a water cooled loop and overclocking it to oblivion and to its limit): 7970(the 670 is a fine overclocker if you are going to push it a good amount, though the only models that really allow full voltage control on gtx models are MSI models)
    Are you planning on ever moving out of the 1920x1080 resolution and going higher: 7970


    its all decision. really. both are already OP for 1 monitor at 1920x1080
  6. I don't plan on going above 1080p as i still run 1680x1050 with a vga to dvi adapter.

    So which card would you go for? i see alot of people compare the 7970 to the 680 so surely the 7970 is better but i just don't know :L
  7. The 670 and 7970 are both best bang for buck so it basically would boil down to which games you play if you care about Adaptive VSync what res monitor do you want to do anything else like use OpenCL applications, transcoding, WPA/WEP Cracking, RAR Cracking, Bitcoin Mining etc Video cards are so much more than just FPS. It is a larger construct of value proposition based upon your desired level of gaming.


    1. What is the best playable experience I can get with current games with THIS card?
    2. How is the driver support for THIS card?
    3. How loud is THIS card?
    4. How much does THIS card cost?
    5. How is the vendor support/warranty for THIS card?
    those are some of the basic things you should ask when looking to buy a card imho.When you ask which is better between a AMD card or a nvidia all that your going to get is confused or brain washed,neither is better it depends on what your doing.
  8. give me 20 minutes we will compare the two cards in question if this is for gaming only edit sorry noway to i can't find a review of that 7970 with current drivers.
  9. If I were you I'd stick with 6970 for a few more month, AMD typically release their top end card(Jan 3rd this year for 7970) early January so you can expect to see some HD 8970 reviews late December.

    Only get a 7970/670 now if you are really having problem playing BF3 on 1080p with 6970 (I doubt it).

    If you have the money for it then get 8970 since it will be the best single card solution, plus you can get 7970 cheap then as well, it is only a 3 month wait.

    Here is an early september review of 7950 Vapor-X, the drivers used are pretty up to date:



    Playing 1080p with no AA with your 6970 should yield a mid 50s FPS which imo is good enough to allow you to wait 3 month for either a cheaper 7970/670 or get the next gen card.
  10. I have about £350 so should i wait for the next series?

    Could you save another 100 to 150 in 3 month? If so I'd get the next series when they come out, if not I get a 7970 next year when their price drop. 7970 launched at $549/500 Euro.

    That is a good idea imo :)
  13. Yea ill probs get around £200 more at xmas and i have £100 on its way atm. So does anyone have any LEGIT info on the new series?
  14. I might get a 670/7970 though still, hard decision. I don't really feel like paying £450-500 for a graphics card.

    We know it will be better since it will be built on more matured 28nm architecture, but the discussion on OCN suggests about 20% improvement in GPGPU and 30-50% in Gaming performance.
  16. Damn 30-50% in gaming performance, i think i might just have to wait since im only really playing BF3 at the moment and my 6870 can play it fine at high/medium settings.

    Are the 8000 cards coming out in December ?

    Offical release will be in January(usually first week for flagship card like 8970, 8950 maybe end of the month), but there will be some reviews coming out in December for you to gauge if the extra money is worth it.
