7900 GTX or 7900 GT SLI?

Which is best? They both seem to have advantages and disadvantages and I really need help deciding. They both cost about the same so its really just a matter of which is really better.

  1. It is best to get a 512 7900 GTX. Most definetly.

    I have heard this from several people, but correct me if I'm wrong.
  2. I would go with the one GTX and get a SLI board so later you could get two of those. Plsu I am almost :oops: sure that a GTX runs almost as fast as two 7900gt's but I could be wrong. Check benchmarks on this website

    Two 7900GTs in SLI are indeed quite a respectable combo, usually besting a single 7900GTX across the board, albeit at $640 total gpu cost ($320x2)...
  4. Are you saying they best a 7900 GTX 256MB, or a 7900 GTX 512MB, since I believe there are versions of both.

  5. Two 7900GTs inSLI usually best a 7900GTX, which, as far as I know, are only available in 512 versions....
  6. I don't think you can find a game where a 7900GTX will beat two 7900GTs in SLI.
  7. Why would this be? The speed of transfer between the two GPU's in a 512 card is much faster then any transfer rate between two 256's. So, therefore, why would it ever be faster?

    A pair of 7900GTs in SLI vs a single GTX512...(not sure what you meant by "the gtx512's two gpus" comment....; are we not discussing SLI 7900GTs vs a single gtx512?)

    When using split frame rendering at 160x1200, essentially each 7900G is rendering 800x600, which will be faster than a single GTX512 can render 1600x1200...

    SLI performance varies from game to game, but many games receive a 40-50% boost form the 2nd card, and some (FEAR) as high as 80%....

    SLI 7900GTs is rather expensive, however, compared to the $399 that a single 1900XT is available for....
  9. I appologize. I was under the impression that the 7900 GTX was like all the rest of the 512 cards out there, which is actually 2 x 256. As in basicly two cards stiched together, with two fans. I had not taken a close look at a picture of this card.

  10. what I meant was that the cost of the two dont make up for the gain in increase. Which is signicant(as I was corrected)but not THAT significant
