Re: Dual 4890's = a 5870???
Except DX11 is an enormous thing for you did get the cheaper 4890 and be on par with a 5870. You consider dual 4890s beats one 5870. There are no DX11 games on the prospect that you are fascinated in. If you are, then get the 5870. If not, then grab an additional 4890. In games and benchmarks, determine to 2 4890's beat a 5870. That would be a yes. In view of the fact that a GTX295 is on par with a 5870 and two 4890's are superior then a GTX295 you would say yes.
Re: Dual 4890's = a 5870???
You depend on the games. Usually speaking, and in general, the 4890s seem to win immediately at present. Well seeing how one 4870 X2 is corresponding to one 5870, you would say yes for the reason that two 4890 in CrossFireX beats one 4870 X2 Seeing as how a 5870 rids by the side of side or presently on top of a 4870X2, you would anticipate dual 4890's to at least match a 5870.
Re: Dual 4890's = a 5870???
Every GPU be able to drive two monitors. On the other hand, when in Crossfire mode, the second GPU loses its capability to drive the monitors. So with two 4890's not Crossfired, you be able to utilize 4 screens. When they are in Crossfire, they act as one GPU, consequently you be able to merely utilize two screens, together of which necessitate to be hooked up to the primary GPU. With the 4000 series, without using exterior devices, you cannot utilize the screens as one large screen. If you make a decision to game, Crossfire facilitated or not, the game determines to default to the main screen.
Re: Dual 4890's = a 5870???
That might depend on the game. Some games do not necessitate a full width desktop to utilize together monitors (supreme commander, burnout paradise). If there is a multi monitor alternative in the game, you would say the crossfire setup determine to be capable to accelerate the 2nd monitor as well if it's hooked up to the most important GPU.
Re: Dual 4890's = a 5870???
So you are saying if you twist off full screen then force the declaration and let it go onto the additional screen. If that runs, that's tremendous. Except for one thing you presently realized. When in Crossfire, there's merely one monitor. So the cards would have to have Crossfire put out of action. You wonder which one would do the rendering. At the least you be familiar with that two monitors be able to work on crossfire within the OS for the reason that you presently have a 22" plugged into one card, and a projector hooked up to the additional card as an extension of your most important display. You would test out playing a game using together display devices but you be familiar with it would not run for the reason that they are 2 totally dissimilar resolutions. Well you have to observe why eyefinity is such a cool characteristic at present you guess. You do not so much mind not being capable to utilize together monitors at the same time as in a game you suppose, but regardless you would still similar to be familiar with if it is probable.
Re: Dual 4890's = a 5870???
No, I am not saying to stretch in excess of 2 screens. So in crossfire you do not even observe the second monitor, you cannot even demonstrate 2d on it. In that case I guess you are screwed. My simple 8800GTS does not put out of action the 2nd monitor when I game on the 1st, I did not imagine crossfire did that. If you have them together hooked up to the most important card, it determines to be there. On the other hand, when you are in a game, I was attractive certain it blacked out. I might be capable to verify later at the moment.
