Our fourth 7900 GS we have for this review is the BFG GeForce 7900 GS OC.

As the "OC" implies, the card comes out-of-the-box with a factory overclock, and it happens to have the highest core clock of all of our 7900 GS cards in this review. The BFG 7900 GS OC's core clock is set at 540MHz, a 90MHz increase over the standard NVIDIA 7900 GS, with the memory clock the same as the reference (660MHz). This is an impressive factory overclock, and we are interested to see what kind of performance we will see with this card. Unfortunately, no games are included in the BFG 7900 GS OC's bundle, but the fact that this card is factory overclocked so high as well as its low price more than make up this.

    It's possible I suppose ... but it seems to me that you'd want to attatch the bar to the pcb at more than two points if this is the case. And you might also want to connect it to the slot cover for the added support of the case screw. Granted, I'm not a mechanical engineer, but it seems to me that connecting one part of the pcb to another like this would just move any moment created by the weight of the HSF somewhere else on the pcb.

    I've also never seen a graphics board bend under normal use. Intel motherboards are another story though. :-)

    Whether or not its made for this, I do have a good use for it: having this bar makes it easier to find a place to grab when removing the card. Sometimes it's tough to find a spot on the pcb to grab, and sometimes the HSF solution isn't mounted in such a way that it's stable enough to use either (I distinctly remember the 6600 GT really disliking any contact with the HSF). This doesn't apply to the huge heat-sink-is-bigger-than-my-forearm solutions though -- they're usually bolted on pretty tight.

    I'd have to go with the Leadtek card. Near to the BFG in almost every level of performance, nearly equal in watt consumption, lower heat output under load, a couple of (suspect, I admit) games included. the (maybe) $20 more is worth it for the heat output alone to me.

    Also, why no noise output comparisons?

    Why ATI cards are not overclock in the reviews? Are they bad overclokers? Why are not factory overclock versions? Reply

    ATI's current generation of GPUs have not been good overclockers. It is also not as easy to find ATI factory overclocked cards.

    We will look at ATI overclocking in similar roundups of ATI cards.

    I was hoping to see a 7600GT including in the mix to see what I would have to gain from a 7900gs. :(

    The 7900 GS launch article compared the 7900 GT to the stock 7900 GS, which you can take a look at here:"> We tested these overclocked 7900 GSs on the same system, so you can compare the numbers directly (with the exception of Oblivion which we tested with different quality settings for this article).

    Hmm, only roughly 5FPS more on the 7900GS vs the 7600GT acrossed the board. Thats pretty sad, but I think I know what I'll be doing when I get a conroe system going, I'll be adding another 7600GT for SLI . . . Reply

    across the board is a little off I think ... in bw2 and oblivion, yes the fps difference is low. But when 4.2 fps is the increase over 17 (a 24% difference), you can't ignore it -- it does make a big difference. I would tend to argue that at these very low framerates, a 5 fps difference is much more noticable than the difference between 60 and 120 fps. In most other tests (especially with AA) frame rate differences were much higher in addition to being higher precent differences. Reply

    "The BFG 7900 GS OC's core clock is set at 520MHz, a 70MHz increase over the standard NVIDIA 7900 GS"
    It’s listed at 540MHz everywhere else.

    Is usually written eVGA.

    "Something slightly unique about this 7900 GS..."
    Uniqueness does not come in shades of grey.
