Those results are well within the margin of error. Either way, someone said that the 590 is slower than two 580s, which can't be proven yet. We haven't seen what a 590 can do.

Performance = power
Power = heat

Lower clocked cores require less power and put off less heat.

This seems to be a hard concept for you to grasp. Can you give me any example where things were done differently in the past? Any older dual gpu cards that were faster than its single core 'brother'? Maybe then I could see the possibility of your banter carrying some weight.

Judging by the specs that the 590 is expected to show up with tells me that this will be no different than the past dual gpu cards.

And why do you suppose they used those?

I said the same clocks. And you never linked me to an article that proves the 590 is slower than sli 580s. So your credibility is non existent.

yawn.

You believe what you think, it doesn't mean anything to me, I'm going to go on nvidias past dual gpu card performance vs SLI singles. You haven't given me any reason to believe otherwise except that I won't search google for an article that you can read (obviously you're incapable of searching google on your own).

it's true its all speculation and assumption at the moment but its never the less a fair one when you look at all previous dual gpu cards. but yeah, we'll have to wait and see

Thread Starter 
What I'm more concerned about is Performance/Power Consumption ratio. I believe GTX580 would win in both categories w/o sweat. Additionally, I'm sick and tired of multi-gpu solutions, they always require special treatment from developers/vendors to fully open up their potential. As an example, had to wait for a few months after SC2 was released to get a normal Crossfire profile.

A single 580 would be your answer.

Ugg. Me as well as many others have issues with the new drivers with the 4870x2. BSOD, instability, etc

had them since 2009 till I upgraded it to a 5850 last year ..

and actually I always used to (game among other things) on my HTPC until late last year
