When we took a look at the Radeon HD 7770, we found that the card has the strong potential to take the new top spot, in the gamers eyes, as the number one DirectX 11 enabled card available on the market. We also found that on its own it has the ability to compete directly with the 6850. We don’t want to go too far into that area though as that is all covered over in each of the 7770 reviews.

What we aim to see here is how a pair of entry level cards fair in relation to a series of higher rated cards and whether or not they are a worth while upgrade. From looking at a pair of 7750′s in CrossFire, we found that AMD’s 2x scaling was taking to the full effect and the performance gains were almost a direct 100% increase, if not more in some cases.

Going by these results and seeing what the 7770 is able to give on its own, we have a very high level of optimism that two 7770′s in CrossFire may be able to give the same levels of performance gain, which for the everyday user is a huge selling point and ever more of a reason to spend that bit extra to get the best bang for buck that everyone wishes for.

    Dude nice review, but it would be nice to include minium/average fps in your charts. Also since its crossfire review include % of scaling of the cards per game, and give opinion if microstatering is present (and is it playable or not). Hope my comment will help you in future reviews.

      it would be helpful if you listed the actual settings and AA used in games. default settings means nothing.

    hi there,
    All i can say is wow. It would be great to compare with 7950 card single version.
    Plus it would be great to compare power and temperature since that is going to be affected by crossfire situation.
    I would love to see how the cooling part come along since the crossfire situation forced two card close together.
    thank

    What drivers did you use?

    this helped AMD sell me 2 of the XFX Double D Black ones… what great performance for $330… isn't another card near that price point that is beating a 580… none.

    Very, very bad review these cards are about the same performance as the 6950 in CF.

    "Expecting the pair of entry-level cards to take on a GTX 580 was not something that was forseen and to say we’re astonished is an understatement." They don't in every game you did not test… they are between the 6950 and 6970 if you test alot of games. Basically all the games and benchmarks you tested are the only ones it does great in. I own the 7970 btw and have two 7770 in media PCs'. These are not that good and in newer games they will suck bad in CF.

    Having bought 2 cards based on this review and having used a 7950 and currently owning a GTX 480 I expected about the same performance just less heat noise etc. What I got was exactly as this review states great performance.

    3DMark 11 6974 P score, Heaven 1796 71.3FPS I own 2 Sapphire OC editions running on a FX6100 @ 4.6Ghz Gaming res 1680×1050. These cards are very good value to the casual gamer.

    R7770 was used xfx black edition or super overclocked overcloked???

  • Notsureaboutcrssfire

    Im wondering if the settings on the Unigine were maxed out or was it just the resolution that changed.

    I have a pair of Asus HD 7770 cards top oc and I think they are great for the price. I run 3 monitors 2x DVI and 1x DP and it handles them fine. I can play BF3 ultru graphics with antialiasing turned down a bit but really these cards are in my oppinion one of the best u can buy for the price.

      question, what driver version are you using for your crossfire setup. I have a pair of Gigabyte 7770′s that are the exact same card i’m attempting to run on my ASUS m5a97 r2.0 motherboard and the system crashes whenever install the current 13.4 catalyst suite. they both run fine on their own in either slot i’ve tested but can’t get them to work together. Any info you could provide would be appreciated.
