Gigabyte GTX 670 OC 2 gb vs Gigabytes radeon hd 7970 OC ???

Hi guys,

Im about to order my pc on and im sure about everything except the graphic card...

Heres my specs

CPU: Intel Core i5-3570k 3.4GHz Quad-Core Processor
Motherboard: P8Z77-V LK
Memory:G.Skill Ripjaws X F3 1600 Mhz DDR3
Storage: Western Digital Caviar Black 1TB 3.5" 7200RPM Internal Hard Drive
Storage: Crucial M4 256GB SSD
Case: Zalman Z9 Plus
Power Supply: EVGA 750W
Optical Drive: Liteon 24x DVD writer
Monitor: Asus VE247H 23.6 inch 1080p 2ms
Operating System: Microsoft Windows 7

I will use this pc only for gaming , i have a mac for all others applications...
I would like to play to...

skyrim with mods
battlefield 3 and 4 soon
farcry 3
crysis 3
Flight simulator X
And all future other games

I've done research about both of them one review they say to go with the gtx and on the other they say to go with the radeon... I saw a couple of bechmark and both are quiet similar in 1080p but the 7970 is better with higher resolution...
(Im going to have one 1080p monitor)

So I did go on gigabytes website and compare both
Comparaison :,4211
Memory are 2gb gtx vs 3 gb radeon
Memory bus 256bit gtx vs 384bit radeon
Core clock 1006 gtx vs 1000 radeon

I always had intel cpu /nvidia graphic card , never touch the amd cpu/radeon so im little bit scary lol

I really dont know what to do ... And I need to order it as soon as possible.

Thank you all !!

  1. both are very solid cards, the question is witch one is cheaper and on sale.

    since both cards will be more than enought for some time to come :)

    id say go with whatevers cheaper and games dont require more than 2gigs of vram atm so yeah.

    whatver is on sale at this moment.
  2. The difference is 40$ between both and I dont care about that little difference ... Some people said that skyrim with mod use 3 gb og vram is that true ? Thats why I dont know what to do between both...

    Does the 258 bit versus the 384bit is a big deal ? On what its gonna help?
  3. Both are comparable cards. You will be hard pressed to see any difference between them without a synthetic FPS benchmark.
    And, one might be better than the other, depending on the game.
    Ignore the specs, they are all folded into the overall performance metric.
    The engineers select those specs to maximize the value at every price point.
    The specs apply to different architectures, and are not directly comparable.

    For you, I would go with the Nvidia card since you are comfortable with their drivers.

    Another possibility which you might consider is consistency of response time.
    I recently read this article comparing a GTX660ti and a 7950.
    It might also apply to a GTX670 and 7970:

    Also, I think that the amount of Vram might be mostly marketing hype.

  4. great thanks for the article im gonna read it right now !
  5. both are good, id say go with whatever u prefer, some games runa bit faster on amd and some on nvidia, so it depends on what games ur playing tbh, but both cards are very close in performance,
  6. Best answer
    Both cards will max out all current games at 1080p. I have done a research about these two cards for like 2 straight weeks, almost read every review, benchmark and debates and I finally went with the GTX 670. You can't go wrong with either cards at this resolution I believe. HOWEVER, I guess you should make your choice based on the games you mostly play and check out benchmarks for them. For instance, if you play BF3, Crysis 2, Starcraft II... GTX 670 will be a better choice. But if you play Dirt, Witcher 2, Skyrim... AMD HD 7970 will be a better choice. But anyway in that resolution, 670 can beat 7970 and vice versa in many games but you won't feel any difference since it will be about 3-5 fps difference up and down no matter the game favors nvidia or amd.

  8. Perfect so I think Im gonna stick with nvidia!

    And if the gtx670 is not enough for the next battlefield 4 , I will just need to put another one in SLI :)
  9. Gigabytes 670 is voltage locked, so just remember that. They are both good cards.

    What do you mean by voltage locked ???
  11. means u cannot adjust the voltage to get an even better overclock, but u dont need to

    mess with voltage to get a good oc anyways.
  12. Ok sndmthe radeon is also locked right ? So i can only oc by the frequency ?
    The gtx 670 oc is not already overclocked ?
  13. thats right, if he says the voltage is locked meaning u cannot adjust the voltage.

    and yes it comes factory overclocked, hence the name oc=overclocked edition
